[CIR] Upstream cir-canonicalize pass (#131891)
This change introduces the cir-canonicalize pass. This is a simple
cir-to-cir transformation that eliminates empty scopes and redundant
branches. It will be expanded in future changes to simplify other
redundant instruction sequences.

MLIR verification and mlir-specific command-line option handling is also
introduced here.
