crypto: x86/aesni - update docs for aesni-intel module

Browse Source 
Update the kconfig help and module description to reflect that VAES
instructions are now used in some cases.  Also fix XTR => XCTR.

Architecture: x86 (32-bit and 64-bit) using:
- AES-NI (AES new instructions)
- VAES (Vector AES)
Some algorithm implementations are supported only in 64-bit builds,
and some have additional prerequisites such as AVX2 or AVX512.
