Currently we cache names and consts in the interpreter. This makes looking up names and consts faster, but slows down calls, returns, yields and sends.

Removing these values has two benefits:

  1. It allows objects other than code objects to be the "code" in a frame, see Make it easier to traverse the frame stack for third party tools. #100987 for why this is a good thing.
  2. It allows the interpreter to execute a limited set of sequences of bytecodes, without requiring them to belong to a code object which cleans up the code for shims and trampolines (which will need more of in the future).

Performance changes show the usual level of noise, with a mean 0.8% speedup.
But the speedups are likely due to faster call/return send/yield sequences, and the slowdowns due to slower LOAD_CONST.
I'm not too concerned about the later, because the tier 2 interpreter will want to fetch its constants from the superblock, not the code object.

Skipping news as this has no observable effect at either Python or C-API level.

pythonGH-100987: Don't cache references to the names and consts array…

… in `_PyEval_EvalFrameDefault`. (python#102640)

* Rename local variables, names and consts, from the interpeter loop. Will allow non-code objects in frames for better introspection of C builtins and extensions.

* Remove unused dummy variables.
