pythonGH-143651) (python#144662) pythongh-143650: Fix importlib race condition on import failure (pythonGH-143651) Fix a race condition where a thread could receive a partially-initialized module when another thread's import fails. The race occurs when: 1. Thread 1 starts importing, adds module to sys.modules 2. Thread 2 sees the module in sys.modules via the fast path 3. Thread 1's import fails, removes module from sys.modules 4. Thread 2 returns a stale module reference not in sys.modules The fix adds verification after the "skip lock" optimization in both Python and C code paths to check if the module is still in sys.modules. If the module was removed (due to import failure), we retry the import so the caller receives the actual exception from the import failure rather than a stale module reference.

Backport of GH-140329 to 3.14, with the addition of:
Enable x86_64 trampoline support on all x86_64 platforms, not just
macOS. While currently only macOS emits X86_64_RELOC_BRANCH
relocations, this ensures the trampoline infrastructure is ready if
future LLVM changes produce out-of-range calls on other x86_64
platforms.
Add error handling to extract_tarball() in get_external.py so that
corrupted or incomplete downloads produce a clear error message
instead of an opaque traceback.
Replace hardcoded LLVM version check in get_externals.bat with
a prefix-based 'llvm-' match using findstr, so future LLVM version
bumps only require changing the version string in one place.
Also, bump the JIT toolchain from LLVM 20 to LLVM 21 (21.1.8). Updated across
CI workflows, build scripts, documentation, and the externals tag.
