Update InternalMatch in subgraph_rewriter after repeated replacements (#99039)
Fixes #98974
When `torch.fx.subgraph_rewriter._replace_pattern` is used to remove nodes from a graph, if there are two adjacent matches then after the first removal, the nodes in `InternalMatch.nodes_map` and `placeholder_nodes` become outdated because they contain nodes that were just removed from the graph.
This fix is to update the `match.nodes_map` and `match.placeholder_nodes` using the node changes stored in `match_changed_node`.
