start treating openssl 3.0 and 1.1 as separate libraries

OpenSSL 3.0 has completely revamed the way applications are supposed to
interact with libcrypto with the old way gaining a hefty perfomance
penalty.

Almost every cryptographic functionality will have a pre-3.0 and
post-3.0 counterpart split by the preprocessor after the migration is
complete.

Instead of having a macros mess everywhere, start the long term plan of
having a cryptographic functionality layer with OpenSSL >=3.0 and
OpenSSL <3.0 as two separate backends.

Start this process by splitting the initialization function.
