OpenSSL and HACL*-based hash functions constructors now support both `data` and `string` parameters.
Previously these constructor functions inconsistently supported sometimes `data` and sometimes `string`,
while the documentation expected `data` to be given in all cases.

gh-134954: Hard-cap max file descriptors in subprocess test fd_status (GH-134955)
* Hard-cap max file descriptors in subprocess test fd_status
On some systems, `SC_OPEN_MAX` may return a very large value (i.e. 10**30), leading to the subprocess test timing out (or run forever).
Prevent this situation by applying a hard cap on how many file descriptors are checked.
* Fix typo in usage docstring

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.

Update `test_io` `_check_warn_on_dealloc` to use `self.` to dispatch to
different I/O implementations.
Update the `_pyio` implementation to match expected behavior, using the
same `_dealloc_warn` design as the C implementation uses to report the
topmost `__del__` object.
The FileIO one now matches all the others, so can use IOBase. There was
a missing check on closing (self._fd must be valid), add that check

If the error handler is used, a new bytes object is created to set as
the object attribute of UnicodeDecodeError, and that bytes object then
replaces the original data. A pointer to the decoded data will became invalid
after destroying that temporary bytes object. So we need other way to return
the first invalid escape from _PyUnicode_DecodeUnicodeEscapeInternal().
_PyBytes_DecodeEscape() does not have such issue, because it does not
use the error handlers registry, but it should be changed for compatibility
with _PyUnicode_DecodeUnicodeEscapeInternal().

The 'help("topics")' output was misaligned due to "ASSIGNMENTEXPRESSIONS"

Reduced the number of columns from 4 to 3 in the listtopics()

In 3.13.3 we accidentally broke the interface for custom task factory. Factory authors added workarounds.
This PR (for 3.13.4) unbreaks task factories that haven't made a workaround yet while also supporting those that have.
NOTE: The custom task factory API will change to what we accidentally released in 3.13.3.
