Fixes #142581

bytes (#138169)
My current internal work requires some sensitivity to IO usage. I had a
work around to calculate the expected size of a Minidump, but I've added
this PR so an automated system could look at the expected size of an
LLDB generated Minidump and then choose if it has the space or wants to
generate it.
There are some prerequisites to calculating the correct size, so I have
the API take a reference for an SBError, I originally tried to return an
SBError and instead take a uint64_t reference, but this made the API
very difficult to use in python.
Added a test case as well.

This patch adds the ability to get a thread at a give index, based on
insertion order, for SBSaveCore Options. This is primarily to benefit
scripts using SBSaveCore, and remove the need to have both options and a
second collection if your script is tracking what threads need to be
saved. Such as if you want to collect the source of all the threads to
be saved after the Core is generated.

Recently in #107731 this change was revereted due to excess memory size
in `TestSkinnyCore`. This was due to a bug where a range's end was being
passed as size. Creating massive memory ranges.
Additionally, and requiring additional review, I added more unit tests
and more verbose logic to the merging of save core memory regions.
@jasonmolenda as an FYI.

Reverts llvm/llvm-project#107159 as this is still causing
`TestSkinnyCorefile.py` to time out.

Reapplies #106293, testing identified issue in the merging code. I used
this opportunity to strip CoreFileMemoryRanges to it's own file and then
add unit tests on it's behavior.

Reverts #105442. Due to `TestSkinnyCoreFailing` and root causing of the
failure will likely take longer than EOD.

This patch removes all of the Set.* methods from Status.
This cleanup is part of a series of patches that make it harder use the
anti-pattern of keeping a long-lives Status object around and updating
it while dropping any errors it contains on the floor.
This patch is largely NFC, the more interesting next steps this enables
is to:
1. remove Status.Clear()
2. assert that Status::operator=() never overwrites an error
3. remove Status::operator=()
Note that step (2) will bring 90% of the benefits for users, and step
(3) will dramatically clean up the error handling code in various
places. In the end my goal is to convert all APIs that are of the form
` ResultTy DoFoo(Status& error)
`
to
` llvm::Expected<ResultTy> DoFoo()
`
How to read this patch?
The interesting changes are in Status.h and Status.cpp, all other
changes are mostly
` perl -pi -e 's/\.SetErrorString/ = Status::FromErrorString/g' $(git
grep -l SetErrorString lldb/source)
`
plus the occasional manual cleanup.

This patch adds the option to specify specific memory ranges to be
included in a given core file. The current implementation lets user
specified ranges either be in addition to a certain save style, or
independent of them via the newly added custom enum.
To achieve being inclusive of save style, I've moved from a std::vector
of ranges to a RangeDataVector, and to join overlapping ranges to
prevent duplication of memory ranges in the core file.
As a non function bonus, when SBSavecore was initially created, the
header was included in the lldb-private interfaces, and I've fixed that
and moved it the forward declare as an oversight. CC @bulbazord in case
we need to include that into swift.

Reapply #100443 and #101770. These were originally reverted due to a
test failure and an MSAN failure. I changed the test attribute to
restrict to x86 (following the other existing tests). I could not
reproduce the test or the MSAN failure and no repo steps were provided.

(#100443)
In #98403 I enabled the SBSaveCoreOptions object, which allows users via
the scripting API to define what they want saved into their core file.
As the first option I've added a threadlist, so users can scan and
identify which threads and corresponding stacks they want to save.
In order to support this, I had to add a new method to `Process.h` on
how we identify which threads are to be saved, and I had to change the
book keeping in minidump to ensure we don't double save the stacks.
Important to @jasonmolenda I also changed the MachO coredump to accept
these new APIs.

overload (#98403)
This PR adds `SBSaveCoreOptions`, which is a container class for options
when LLDB is taking coredumps. For this first iteration this container
just keeps parity with the extant API of `file, style, plugin`. In the
future this options object can be extended to allow users to take a
subset of their core dumps.
