treewide: fix various bugs w/ OpenSSL 3+ EVP API
The OpenSSL 3+ EVP API for SHA-* cannot support our prior use cases
supported by other SHA-* implementations. It has the following
differences:
1. ->init_fn is required before all use
2. struct assignments don't work and requires ->clone_fn
3. can't support ->update_fn after ->final_*fn
While fixing cases 1 and 2 is merely the matter of calling ->init_fn and
->clone_fn as appropriate, fixing case 3 requires calling ->final_*fn on
a temporary context that's cloned from the primary context.
