Remove x86/x86_64 BSAES and AES_ASM support

This leaves VPAES and AESNI support.
The VPAES performance is comparable but BSAES is not
completely constant time. There are table lookups
using secret key data in AES_set_encrypt/decrypt_key
and in ctr mode short data uses the non-constant
time AES_encrypt function instead of bit-slicing.
Furthermore the AES_ASM is by far outperformed
by recent GCC versions.
Since BSAES calls back to AES_ASM for short
data blocks the performance on those is also
worse than the pure software implementaion.

Fixes: #9640
