  -----------
  [MCA][X86] Cleanup znver4 instregex patterns for (V)PMOV extension/truncation instructions

Split extension/truncation patterns to simplify matching.

Fix patterns to consistently match SSE/AVX1/AVX2 variants as well.

Add some missing src/dst type variants - there should be no difference in scheduling, its purely based on dst reg width.

Confirmed with Agner/uops.info

Noticed while triaging #110308
