gh-133711: Fix test_regrtest for PYTHONUTF8=1 (GH-134839)
Use "backslashreplace" error handler to decode stdout and stderr.
Example:
vstinner@WIN C:\victor\python\main\build\test_python_worker_8360\x91>
"C:\victor\python\main\PCbuild\amd64\python_d.exe" -m test
--fast-ci --slow-ci --testdir
C:\Users\vstinner\AppData\Local\Temp\tmp0t59e8da
test_regrtest_noop1 test_regrtest_noop2 test_regrtest_noop3
test_regrtest_noop4
Notice the "\x91" byte at the end of the first line: it's the
non-ASCII U+00E6 character encoded to the OEM cp437 code page.

gh-132493: Remove __annotations__ usage in inspect._signature_is_functionlike (GH-133415)
This check is potentially problematic because it could force evaluation of
annotations unnecessarily. This doesn't trigger for builtin objects (functions,
classes, or modules) with annotations, but it could trigger for third-party objects.
The check was not particularly useful anyway, because it succeeds if ``__annotations__``
is a dict or None, so the only thing this did was guard against objects that have an
``__annotations__`` attribute that is of some other type. That doesn't seem particularly
useful, so I just removed the check.

gh-91048: Refactor and optimize remote debugging module (#134652)
Completely refactor Modules/_remote_debugging_module.c with improved
code organization, replacing scattered reference counting and error
handling with centralized goto error paths. This cleanup improves
maintainability and reduces code duplication throughout the module while
preserving the same external API.
Implement memory page caching optimization in Python/remote_debug.h to
avoid repeated reads of the same memory regions during debugging
operations. The cache stores previously read memory pages and reuses
them for subsequent reads, significantly reducing system calls and
improving performance.
Add code object caching mechanism with a new code_object_generation
field in the interpreter state that tracks when code object caches need
invalidation. This allows efficient reuse of parsed code object metadata
and eliminates redundant processing of the same code objects across
debugging sessions.
Optimize memory operations by replacing multiple individual structure
copies with single bulk reads for the same data structures. This reduces
the number of memory operations and system calls required to gather
debugging information from the target process.
Update Makefile.pre.in to include Python/remote_debug.h in the headers
list, ensuring that changes to the remote debugging header force proper
recompilation of dependent modules and maintain build consistency across
the codebase.
Also, make the module compatible with the free threading build as an extra :)

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.
