gh-133960: Improve typing.evaluate_forward_ref (GH-133961)
As explained in GH-133960, this removes most of the behavior differences with ForwardRef.evaluate.
The remaining difference is about recursive evaluation of forwardrefs; this is practically useful
in cases where an annotation refers to a type alias that itself is string-valued.
This also improves several edge cases that were previously not handled optimally. For example,
the function now takes advantage of the partial evaluation behavior of ForwardRef.evaluate() to
evaluate more ForwardRefs in the FORWARDREF format.
This also fixes GH-133959 as a side effect, because the buggy behavior in GH-133959 derives from
evaluate_forward_ref().

Move from using critical sections to locks for the (de)compression methods.
Since the methods allow other threads to run, we should use a lock rather
than a critical section.

GH-130397: remove special-casing of C stack depth for WASI (GH-134469)
Removed special-casing for WASI when setting C stack depth limits. Since WASI has its own C stack checking this isn't a security risk.
Also disabled some tests that stopped passing. They all happened to have already been disabled under Emscripten.

gh-134309: Add ``github.actor`` to the GitHub Actions concurrency key (GH-134310)
When inexperienced users create a PR from their default branch, all of the concurrency keys

where workflow runs are cancelled on other pull requests.
Disambiguate by adding the username of the relevant 'actor' to the concurrency key.

The `__main__` module imported in the `_pyrepl` module points to the `_pyrepl` module itself when the interpreter was launched without `-m` option and didn't execute a module,
while it's an unexpected behavior that `__main__` can be `_pyrepl` and relative imports such as `from . import *` works based on the `_pyrepl` module.
