Spring 24901 - Fix to handle static part of path variable URI mappings performance

Currently Spring webmvc looks up direct URLs and fall back to evaluating every URL mapped if there is no exact match based on direct URLs mappings. Due to this, URI with path variables, always go through larger look up evaluations poor performance. This PR stores static URIs as part of a MappingRegistry in a new Map to match incoming URIs to identify partial matches to cut down the mapping evaluations and hence improves performance
