[X86] Ensure that bit reversals of byte vectors are properly lowered on pure GFNI targets (#148304)
Fixes #148238.
When GFNI is present, custom bit reversal lowerings for scalar integers
become active. They work by swapping the bytes in the scalar value and
then reversing bits in a vector of bytes. However, the custom bit
reversal lowering for a vector of bytes is disabled if GFNI is present
in isolation, resulting messed up code.
