  Log Message:
  -----------
  [mlir][Vector] Move mask materialization patterns to greedy rewrite (#119973)

The mask materialization patterns during `VectorToLLVM` are rewrite
patterns. They should run as part of the greedy pattern rewrite and not
the dialect conversion. (Rewrite patterns and conversion patterns are
not generally compatible.)

The current combination of rewrite patterns and conversion patterns
triggered an edge case when merging the 1:1 and 1:N dialect conversions.
