Remove need for mutable reference to static (#13705)

Mutable references to static data are inherently unsafe and typically
unsound in Rust, because statics are implicitly shared between threads,
and the borrow checker can only enforce the shared/exclusive reference
limitations within a single thread here.

This just moves the thread-exclusion logic into the individual elements
of the `static`, where the `GILOnceCell` can correctly handle the
runtime exclusion of multiple threads. (The GIL is no longer suitable
for thread exclusion if we were doing a freethreaded Python build, but
that's a problem we have all over Qiskit, and would need to change to
`OnceLock` or the like.)
