  Log Message:
  -----------
  [mlir][GreedyPatternRewriter] Add out param to detect changes in IR in `applyPatternsAndFoldGreedily`

This allows users of `applyPatternsAndFoldGreedily` to detect if any MLIR changes have occurred. An example use-case is where we expect the `applyPatternsAndFoldGreedily` to change the IR and want to validate that it indeed does change it.
