  [SLP][modularisation][NFC] Move BaseShuffleAnalysis to SLPShuffleAnalysis.h (#222236)

Move the BoUpSLP-independent shuffle-analysis base class out of
SLPVectorizer.cpp into a new header-only
SLPVectorizer/SLPShuffleAnalysis.h. BoUpSLP::ShuffleCostEstimator and
BoUpSLP::ShuffleInstructionBuilder keep deriving from it.

createShuffle read the file-local SLPReVec cl::opt in an assert; the
option stays static in SLPVectorizer.cpp and the moved template takes
its value as an explicit bool parameter. Behavior is unchanged.

Part of the SLPVectorizer.cpp modularization effort:
