Ignore PermissionError when checking cwd during import
On macOS `getcwd(3)` can return EACCES if a path component isn't readable,
resulting in PermissionError. `PathFinder.find_spec()` now catches these and
ignores them - the same treatment as a missing/deleted cwd.
Introduces `test.support.os_helper.save_mode(path, ...)`, a context manager
that restores the mode of a path on exit.
This is allows finer control of exception handling and robust environment
restoration across platforms in `FinderTests.test_permission_error_cwd()`.

Since tracemalloc uses PyMutex, it becomes safe to use TABLES_LOCK()
even after _PyTraceMalloc_Fini(): remove the "pre-check" in
PyTraceMalloc_Track() and PyTraceMalloc_Untrack().
PyTraceMalloc_Untrack() no longer needs to acquire the GIL.
_PyTraceMalloc_Fini() can be called earlier during Python
finalization.
This was missing from gh-124640. It's already covered by the new
test_asyncio/test_free_threading.py in combination with the runtime
assertion in set_ts_asyncio_running_task.

We remove the safeguards that were added in `Lib/test/test_capi/test_codecs.py`
since they are now redundant (see 32e07fd377
for additional context).
Indeed, the codecs handlers now correctly handle the `start` and `end` positions
of `UnicodeError` objects and thus should not crash.
Add fast path in PyLong_From*() functions for compact integers.

This adds basic support to override default messages for domain errors
in the math_1() helper. The sqrt(), atanh(), log2(), log10() and log()
functions were modified as examples. New macro supports gradual
changing of error messages in other 1-arg functions.

This fixes how `PyCodec_BackslashReplaceErrors` handles the `start` and `end`
attributes of `UnicodeError` objects via the `_PyUnicodeError_GetParams` helper.
