[3.13] gh-134696: align OpenSSL and HACL*-based hash functions constructors AC signatures (GH-134713) (#134962)

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

    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.
