Madhur Amilkanthwar e6673bd037 [SLP][Modularization][NFC] Extract type and constant helpers into SLPUtils (1/3) (#206881) ...

As we discussed on RFC:
https://discourse.llvm.org/t/modularizing-slpvectorizer-cpp/90922

This patch introduces the SLPVectorizer/ subdirectory and adds
SLPUtils.{h,cpp} under namespace llvm::slpvectorizer, then moves the
type and constant query helpers into it:
  - isConstant
  - isVectorLikeInstWithConstOps
  - isSplat
  - allConstant
  - allSameBlock
  - allSameType
  - allSameOpcode
  - getNumElements
  - getPartNumElems
  - getNumElems
  - getInsertExtractIndex
  - getExtractIndex
