[3.13] gh-128679: Fix tracemalloc.stop() race conditions (#128897) 
tracemalloc_alloc(), tracemalloc_realloc(), PyTraceMalloc_Track(),
PyTraceMalloc_Untrack() and _PyTraceMalloc_TraceRef() now check
tracemalloc_config.tracing after calling TABLES_LOCK().

_PyTraceMalloc_Stop() now protects more code with TABLES_LOCK(),
especially setting tracemalloc_config.tracing to 1.

Add a test using PyTraceMalloc_Track() to test tracemalloc.stop()
race condition.

Call _PyTraceMalloc_Init() at Python startup.

gh-106320: Remove private _PyTraceMalloc C API functions (#106324) 
* Remove private _PyTraceMalloc C API functions: move them to the
  internal C API.
* Don't export most of these functions anymore, but still export
  _PyTraceMalloc_GetTraceback() used by tests.

gh-77532: Minor tweaks to allow compiling with PlatformToolset=ClangCL on Windows (GH-101352) 
To use this, ensure that clang support was selected in Visual Studio Installer, then set the PlatformToolset environment variable to "ClangCL" and build as normal from the command line.
It remains unsupported, but at least is possible now for experimentation.
