[mlir] Change the internal representation of FrozenRewritePatternList to use shared_ptr

This will allow for caching pattern lists across multiple pass instances, such as when multithreading. This is an extremely important invariant for PDL patterns, which are compiled at runtime when the FrozenRewritePatternList is built.
