[NFC][X86][MCA] Add sudo-zero-idiom vperm2f128/vperm2i128 tests - don't break deps 

While btver2 model states that this pattern is a zero-cycle zero-idiom
on Jaguar, it does not appear to be the case on Znver3,
here it measures as not being recognized as dep-breaking zero-idiom,
let alone a zero-cycle one.
