x86: drop Vex128 and Vex256

Browse Source 
These are only used when VEX.L or EVEX.L'L have already been decoded,
and hence the "normal" length dependent name determination is quite
fine. Adjust a few enumerators to make clear that vex_len_table[] has
been consulted; be consistent and do so for all *f128 and *i128 insns
in one go.
