gh-131423: Update OpenSSL data to 3.4.1 on Linux (#131618) 
OpenSSL 3.4.1 mnemonics are not compatible with OpenSSL 3.4.0 ones since
they were renumbered [1, 2]. Consequently, `_ssl_data_34.h` is renamed to
`_ssl_data_340.h` and `_ssl_data_34.h` now contains OpenSSL 3.4.1 mnemonics.

We also refine the mnemonics that are selected, discarding those that are
mnemonic-like but should not be used as such. More precisely, we remove
the ERR_LIB_MASK and ERR_LIB_OFFSET entries from OpenSSL 1.1.1 data.

gh-99108: Implement HACL* HMAC (#130157) 
A new extension module, `_hmac`, now exposes the HACL* HMAC (formally verified) implementation.

The HACL* implementation is used as a fallback implementation when the OpenSSL implementation of HMAC
is not available or disabled. For now, only named hash algorithms are recognized and SIMD support provided
by HACL* for the BLAKE2 hash functions is not yet used.

Add free-threaded versions of existing specialization for FOR_ITER (list, tuples, fast range iterators and generators), without significantly affecting their thread-safety. (Iterating over shared lists/tuples/ranges should be fine like before. Reusing iterators between threads is not fine, like before. Sharing generators between threads is a recipe for significant crashes, like before.)
