* Py_GetCompiler()
* Py_GetCopyright()
* Py_GetPlatform()
* Py_GetVersion()
Changes:
* Add Modules/_testlimitedcapi.c and
Lib/test/test_capi/test_build.py files.
* Add internal _Py_GetBuiltWithAssert() function.
* Reimplemenet support.built_with_c_assertions() using
_Py_GetBuiltWithAssert() to cover more cases like buildbots using
CFLAGS=-UNDEBUG in release mode.

Add _testcapi helpers to create a capsule with an arbitrary name and to call PyCapsule_Import(), and Python tests covering the current behavior: only the first component of the dotted name is imported, the rest are attribute lookups.

gh-136421: Load `_datetime` static types during interpreter initialization (GH-136583)
`_datetime` is a special module, because it's the only non-builtin C extension that contains static types. As such, it would initialize static types in the module's execution function, which can run concurrently. Since static type initialization is not thread-safe, this caused crashes. This fixes it by moving the initialization of `_datetime`'s static types to interpreter startup (where all other static types are initialized), which is already properly protected through other locks.

Extension builders must specify Py_GIL_DISABLED if they want to link to the free-threaded builds.
This was usually the case already, but this change guarantees it in all circumstances.
Make `warnings.catch_warnings()` use a context variable for holding
the warning filtering state if the `sys.flags.context_aware_warnings`
flag is set to true. This makes using the context manager thread-safe in
multi-threaded programs.
Add the `sys.flags.thread_inherit_context` flag. If true, starting a new
thread with `threading.Thread` will use a copy of the context
from the caller of `Thread.start()`.
Both these flags are set to true by default for the free-threaded build
and false for the default build.
Move the Python implementation of warnings.py into _py_warnings.py.
Make _contextvars a builtin module.
