gh-143414: Implement unique reference tracking for JIT, optimize unpacking of such tuples

[reidenong]

1. Implements unique reference tracking to references in the JIT Optimizer.
2. Uses the unique reference tracking to eliminate unnecessary reference counting for uniquely referenced tuples. ex:

x, y, z = f()

Some notes:

• Only implements the unique reference tracking (and relevant optimization) for tuples in _BUILD_TUPLE, to be extended to other objects in the future
• Objects are deemed as not uniquely referenced when they are made aliases or duplicated, in uops of _LOAD_FAST_* and _COPY.

Would appreciate any feedback.
Thanks

Discussed with @Fidget-Spinner, will reopen the PR after implementing PyStackRef_CLOSE_SPECIALIZED for _UNPACK_SEQUENCE_UNIQUE_TUPLE
