This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

In API tests, replace use of the `p` alias with the `expression` command.
To avoid conflating tests of the alias with tests of the expression command,
this patch canonicalizes to the use `expression`.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

This patch removes the infrastructure to replay the test suite from a
reproducer, as well as the modifications made to the individual tests.

expressions
LLDB is currently always activating C++ when parsing expressions as LLDB itself
is using C++ features when creating the final AST that will be codegen'd
(specifically, references to variables, namespaces and using declarations are
used).
This is causing problems for users that have variables in non-C++ programs (e.g.
plain C or Objective-C) that have names which are keywords in C++. Expressions
referencing those variables fail to parse as LLDB's Clang parser thinks those
identifiers are C++ keywords and not identifiers that may belong to a
declaration.
We can't just disable C++ in the expression parser for those situations as
replacing the functionality of the injected C++ code isn't trivial. So this
patch is just disabling most keywords that are exclusive to C++ in LLDB's Clang
parser when we are in a non-C++ expression. There are a few keywords we can't
disable for now:
* `using` as that's currently used in some situations to inject variables into the expression function.
* `__null` as that's used by LLDB to define `NULL`/`Nil`/`nil`.
Getting rid of these last two keywords is possible but is a large enough change
that this will be handled in follow up patches.
Note that this only changes the keyword status of those tokens but this patch
does not remove any C++ functionality from the expression parser. The type
system still follows C++ rules and so does the rest of the expression parser.
There is another small change that gives the hardcoded macro definitions in LLDB
a higher precedence than the macros imported from the Objective-C modules. The
reason for this is that the Objective-C modules in LLDB are actually parsed in
Objective-C++ mode and they end up providing the C++ definitions of certain
system macros (like `NULL` being defined as `nullptr`). So we have to move the
LLDB definition forward and surround the definition from the module with an
`#ifdef` to make sure that we use the correct LLDB definition that doesn't
reference C++ keywords. Or to give an example, this is how the expression source
code changes:
Before:
```
#define NULL (nullptr) // injected module definition
#ifndef NULL
#define NULL (__null) // hardcoded LLDB definition
#endif
```
After:
```
#ifndef NULL
#define NULL (__null) // hardcoded LLDB definition
#endif
#ifndef NULL
#define NULL (nullptr) // injected module definition
#endif
```

Replace the plethora of ObjC-implied 'skipUnlessDarwin' decorators
with marking tests as 'objc' category (whenever missing), and skip all
ObjC tests on non-Darwin platforms. I have used '.categories' file
wherever it was present already or all (>1) tests were relying on ObjC,
and explicit add_test_categories() where there was only one test.

Add the skipIfReproducer decorator to the remaining tests that fail to
replay because the GDB remote packets diverge during replay. This is
*not* expected and should be fixed, but figuring out exactly what caused
the divergence has proven pretty difficult to track down.
I've marked these tests as skipped for now so we can get clean results
and detect new regressions. I have no evidence to believe that these
failures have the same root cause, so I've not assigned them a PR.

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
