gh-127266: avoid data races when updating type slots (gh-131174)
In the free-threaded build, avoid data races caused by updating type slots
or type flags after the type was initially created.  For those (typically
rare) cases, use the stop-the-world mechanism.  Remove the use of atomics
when reading or writing type flags.  The use of atomics is not sufficient to
avoid races (since flags are sometimes read without a lock and without
atomics) and are no longer required.

gh-128384: Use a context variable for warnings.catch_warnings (gh-130010)
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.

gh-131238: Move pycore_obmalloc.h include to pycore_runtime_structs.h (#131482)
Move pycore_obmalloc.h include from pycore_interp_structs.h to
pycore_runtime_structs.h.

Add also comment explaining the purpose of each include in
pycore_interp_structs.h, pycore_runtime_structs.h and
pycore_structs.h.

Remove <stdbool.h> and <stddef.h> from pycore_structs.h.
