[VectorCombine] foldBitcastShuf - add support for length changing shuffles
Allow length changing shuffle masks in the "bitcast (shuf V, MaskC) --> shuf (bitcast V), MaskC'" fold.
It also exposes some poor shuffle mask detection for extract/insert subvector cases inside improveShuffleKindFromMask
First stage towards addressing Issue #67803
