This commit aggregates the following changes:
1. Fix the format (i.e., indentation) when printing stop hooks via `target
stop-hook list`.
2. Add `IndentScope Stream::MakeIndentScope()` to make managing (and restoring!)
of the indentation level on `Stream` instances more ergonomic and less error
prone.
3. Simplify printing of stop hooks using the new `IndentScope`.

Fixes https://github.com/llvm/llvm-project/issues/57372
Previously some work has already been done on this. A PR was generated
but it remained in review:
https://reviews.llvm.org/D136462
In short previous approach was following:
Changing the symbol names (making the searched part colorized) ->
printing them -> restoring the symbol names back in their original form.
The reviewers suggested that instead of changing the symbol table, this
colorization should be done in the dump functions itself. Our strategy
involves passing the searched regex pattern to the existing dump
functions responsible for printing information about the searched
symbol. This pattern is propagated until it reaches the line in the dump
functions responsible for displaying symbol information on screen.
At this point, we've introduced a new function called
"PutCStringColorHighlighted," which takes the searched pattern, a prefix and suffix,
and the text and applies colorization to highlight the pattern in the
output. This approach aims to streamline the symbol search process to
improve readability of search results.

Applied modernize-use-default-member-init clang-tidy check over LLDB.
It appears in many files we had already switched to in class member init but
never updated the constructors to reflect that. This check is already present in
the lldb/.clang-tidy config.

I was looking at Stream::PutRawBytes and thought I spotted a bug because
both loops are using `i < src_len` as the loop condition despite them
iterating in opposite directions.
On closer inspection, the existing code is correct, because it relies on
well-defined unsigned integer wrapping. Correct doesn't mean readable,
so this patch changes the loop condition to compare against 0 when
decrementing i while still covering the edge case of src_len potentially
being 0 itself.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

them take raw_ostream
Summary:
Yet another step on the long road towards getting rid of lldb's Stream class.
We probably should just make this some kind of member of Address/AddressRange, but it seems quite often we just push
in random integers in there and this is just about getting rid of Stream and not improving arbitrary APIs.
I had to rename another `DumpAddress` function in FormatEntity that is dumping the content of an address to make Clang happy.

llvm::raw_ostream provides equivalent functionality.
|

We expect it to be always positive values and LLVM/Clang's IndentLevel
values are already unsigned integers, so we should do the same.

Summary:
I recently re-discovered that the unsinged stream operators of the
lldb_private::Stream class have a surprising behavior in that they print
the number in hex. This is all the more confusing because the "signed"
versions of those operators behave normally.
Now that, thanks to Raphael, each Stream class has a llvm::raw_ostream
wrapper, I think we should delete most of our formatting capabilities
and just delegate to that. This patch tests the water by just deleting
the operators with the most surprising behavior.
Most of the code using these operators was printing user_id_t values. It
wasn't fully consistent about prefixing them with "0x", but I've tried
to consistenly print it without that prefix, to make it more obviously
different from pointer values.

Replaces the remaining C-style casts with explicit casts in Utility. The
motivation is that they are (1) easier to spot and (2) don't have

A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
This patch removes the manual byte counting in all internal Stream methods.
This is now done by the automatic byte counting provided by calling `GetWrittenBytes()`
before and after writing the data (which is automatically done for us by the `ByteDelta`
utility class).

Summary:
This wrapper will allow us in the future to reuse LLVM methods from within the
Stream class.
Currently no test as this is intended to be an internal class that shouldn't have any
NFC. The test for this change will be the follow up patch that migrates LLDB's
LEB128 implementation to the one from LLVM.
This change also adds custom move/assignment methods to Stream, as LLVM
raw_ostream doesn't support these. As our internal stream has anyway no state,
we can just keep the same stream object around.

Summary:
When I added the Stream unit test (r338488), the build bots failed due to an out-of-
bound reads when passing an empty string to the PutCStringAsRawHex8 method.
In r338491 I removed the test case to fix the bots.
This patch fixes this in PutCStringAsRawHex8 by always checking for the terminating
null character in the given string (instead of skipping it the first time). It also re-adds the
test case I removed.

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:
import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
header = ""
text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)
continue
if text:
text += " " + match.group(2)
else:
header = match.group(1)
text = match.group(2)
continue
if text:
filled = textwrap.wrap(text, width=(78-len(header)),
break_long_words=False)
for l in filled:
out.write(header+" "+l+'\n')
text = ""
out.write(line)
os.rename(tmp, sys.argv[1])

This patch makes adjustments to header file includes in
lldbUtility based on recommendations by the iwyu tool
(include-what-you-use). The goal here is to make sure that
all files include the exact set of headers which are needed
for that file only, to eliminate cases of dead includes (e.g.
someone deleted some code but forgot to delete the header
includes that that code necessitated), and to eliminate the
case where header includes are picked up transitively.

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.
