Victor Stinner 36c5e3bcc2 gh-128679: Redesign tracemalloc locking (#128888) 
* Use TABLES_LOCK() to protect 'tracemalloc_config.tracing'.
* Hold TABLES_LOCK() longer while accessing tables.
* tracemalloc_realloc() and tracemalloc_free() no longer
  remove the trace on reentrant call.
* _PyTraceMalloc_Stop() unregisters _PyTraceMalloc_TraceRef().
* _PyTraceMalloc_GetTraces() sets the reentrant flag.
* tracemalloc_clear_traces_unlocked() sets the reentrant flag.

* Don't export most of these functions anymore, but still export
  _PyTraceMalloc_GetTraceback() used by tests.

Steve Dower 737d367b1f 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.
