  [MLIR][SCF] Sink scf.if from scf.while before region into after region in scf-uplift-while-to-for (#165216)

When a `scf.if` directly precedes an `scf.condition` in the before
region of an `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`.
