[x64] Add kX64EmitGFNI emitter feature-flag

Browse Source 
This determines support for the `gf2p8affineqb` instruction. Even though `GFNI` is typically found with AVX512-enabled chips, it _is_ possible for there to be a chip with `GFNI` but does not support `AVX` or `AVX2` of any sort. An example of this is Tremont(Lakefield) chips as well as Jasper Lake.
