ARMeilleure: Add `gfni` acceleration (#3669)
* ARMeilleure: Add `GFNI` detection
This is intended for utilizing the `gf2p8affineqb` instruction
* ARMeilleure: Add `gf2p8affineqb`
Not using the VEX or EVEX-form of this instruction is intentional. There
are `GFNI`-chips that do not support AVX(so no VEX encoding) such as
Tremont(Lakefield) chips as well as Jasper Lake.

* ARMeilleure: Add `gfni` acceleration of `Rbit_V`
Passes all `Rbit_V*` unit tests on my `i9-11900k`
* ARMeilleure: Add `gfni` acceleration of `S{l,r}i_V`
Also added a fast-path for when the shift amount is greater than the
size of the element.
* ARMeilleure: Add `gfni` acceleration of `Shl_V` and `Sshr_V`
* ARMeilleure: Increment InternalVersion
* ARMeilleure: Fix Intrinsic and Assembler Table alignment
`gf2p8affineqb` is the longest instruction name I know of. It shouldn't
get any wider than this.
* ARMeilleure: Remove SSE2+SHA requirement for GFNI
* ARMeilleure Add `X86GetGf2p8LogicalShiftLeft`
Used to generate GF(2^8) 8x8 bit-matrices for bit-shifting for the `gf2p8affineqb` instruction.
* ARMeilleure: Append `FeatureInfo7Ecx` to `FeatureInfo`
