Description: When OpenSSL is configured to only load "base+fips" providers into the Null library context, md5 might not be available at all. In such cases currently CPython fallsback to internal hashlib implementation is there is one - as there might not be if one compiles python with --with-builtin-hashlib-hashes=blake2. With this change "default" provider is attempted to be loaded to access nonsecurity hashes. It is FedRAMP/FIPS compliance by-pass. This issue may allow using md5 without specifying "usedforsecurity=False" on systems otherwise configured to be in FIPS-mode only. And is the primary reason why documentation mentions that certain distributions of python remove md5 module altogether. Issue: gh-118224
