  [MLIR] Handle materializeConstant failure in GreedyPatternRewriteDriver (#77258)

Make GreedyPatternRewriteDriver handle failures of `materializeConstant`
gracefully. Previously it was not checking whether the returned op was
null and crashing. This PR handles it similarly to how OperationFolder
does it.
