gh-152075: Avoid lock contention in _Py_Specialize_LoadGlobal under free threading (gh-153720)

Under high thread concurrency in free-threaded builds, `_Py_Specialize_LoadGlobal` suffers from lock contention when acquiring the critical section mutexes for the `globals` and `builtins` dictionaries during bytecode specialization.

This PR skips LOAD_GLOBAL bytecode specialization if acquiring the two object mutexes would block.
