  [MLIR][SCF] Canonicalize redundant scf.if from scf.while before region into after region (#169892)

When a `scf.if` directly precedes a `scf.condition` in the before region
of a `scf.while` and both share the same condition, move the if into the
after region of the loop. This helps simplify the control flow to enable
uplifting `scf.while` to `scf.for`.
