Add Sse2.MoveMask that takes Vector128<byte>

[eerhardt]

Today we have overloads for Avx2.MoveMask for both sbyte and byte vectors.

• Avx2.MoveMask(Vector256<sbyte> value)
• Avx2.MoveMask(Vector256<byte> value)

but for Sse2, we only have overloads for sbyte.

• Sse2.MoveMask(Vector128<sbyte> value)

We should add an Sse2.MoveMask overload that takes a Vector128<byte> as well.

Does this necessarily qualify as an API-suggestion? I would think it was one of the already approved APIs that was missed due to different review process taken for these APIs...

Yes, My apologies...

No, I don't think this has to go through the full API review process. It should have been included in the initial review. I just wanted to ensure people saw this as an "API modifying" issue.
