cmd/internal/obj/x86: add missing Yi8 for VEX ytabs

Browse Source 
This change adds Yi8 forms for every ytab that had them before AVX-512 patch.
The rationale is backwards-compatibility.

EVEX forms remain strict and unchanged as they're not bound to any
backwards-compatibility issues.

Fixes #25510
