gh-117657: Replace TSAN suppresions with more specific rules (#118722)

Using `race:` filters out warnings if the function appears anywhere in
the stack trace. This can hide a lot of unrelated warnings, especially
for a function like `_PyEval_EvalFrameDefault`, which is somewhere on
the stack more often than not.

Change all free-threaded suppressions to `race_top:`, which only matches
the top frame, and add any new suppressions this exposes.
