gh-131423: Update to OpenSSL 3.0.16. (GH-131839) 
The bin tag is 3.0.16.1 because we rebuilt without uplink support to fix gh-131804.
This PR also prevents making calls that are now unsafe without uplink, and updates
the tests to property interpret these failures as unsupported.

gh-131586: Avoid refcount contention in some "special" calls (#131588) 
In the free threaded build, the `_PyObject_LookupSpecial()` call can lead to
reference count contention on the returned function object becuase it
doesn't use stackrefs. Refactor some of the callers to use
`_PyObject_MaybeCallSpecialNoArgs`, which uses stackrefs internally.

This fixes the scaling bottleneck in the "lookup_special" microbenchmark
in `ftscalingbench.py`. However, the are still some uses of
`_PyObject_LookupSpecial()` that need to be addressed in future PRs.

gh-131418: remove unused legacy typedefs in {md5,sha1}module.c (#131420) 
- Remove legacy typedefs `MD5_INT32` and `MD5_INT64` in `Modules/md5module.c`
- Remove legacy typedefs `SHA1_INT32` and `SHA1_INT64` in `Modules/sha1module.c`.

Those legacy typedefs were used to detect whether the host platform could
correctly implement MD5 and SHA-1, but this is no longer needed as we now
fallback to HACL* implementations.

- raise_ssl_error(): set an exception from the last SSL error code or use a user-defined message.
- notify_ssl_error_occurred(): same as raise_ssl_error() but with a generic default message.
