This uses [teyit](https://pypi.org/project/teyit/) to modernize asserts,
as recommended by the [unittest release
notes](https://docs.python.org/3.12/whatsnew/3.12.html#id3).
For example, `assertTrue(a == b)` is replaced with `assertEqual(a, b)`.
This produces better error messages, e.g. `error: unexpectedly found 1
and 2 to be different` instead of `error: False`.
assertEquals is a deprecated alias for assertEqual and has been removed
in Python 3.12. This wasn't an issue previously because we used a
vendored version of the unittest module. Now that we use the built-in
version this gets updated together with the Python version used to run
the test suite.
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.

We recently had an issue where a user declared a `Class::free` function which
then got picked up by accident by the expression evaluator when calling
`::free`. This was due to a too lax filter in the DWARFIndex (which was fixed by
https://reviews.llvm.org/D73191 ). This broke the Objective-C utility expression
that is trying to update the Objective-C class list (which is calling `:;free`).
This adds a regression test for situations where we have a bunch of functions
defined that share the name of the global functions that this utility function
calls. None of them are actually conflicting with the global functions we are
trying to call (they are all in namespaces, objects or classes).

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
```

Display null pointer as `nullptr`, `nil` and `NULL` for C++,
Objective-C/Objective-C++ and C respectively. The original motivation
for this patch was to display a null std::string pointer as nullptr
instead of "", but the fix seemed generic enough to be done for all
summary providers.

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.

Use skipUnlessDarwin decorator for tests that are specific to Darwin,
instead of skipIf... for all other platforms. This should make it clear
that these tests are not supposed to work elsewhere. It will also make
these tests stop repeatedly popping up while I look for tests that could
be fixed on the platform in question.

and delete a bunch (but not all) redundant code. If you compare the remaining implementations of Platform*Simulator.cpp, there is still an obvious leftover cleanup task.
Specifically, this patch
- removes SDK initialization from dotest (there is equivalent but more
complete code in Makefile.rules)
- make Platform*Simulator inherit the generic implementation of
PlatformAppleSimulator (more can be done here)
- simplify the platform logic in Makefile.rules
- replace the custom SDK finding logic in Platform*Simulator with XcodeSDK
- adds a test for each supported simulator

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.
