Prior to this commit, `SimpleUrlHandlerMapping` and other
implementations of `AbstractUrlHandlerMapping` would not strip the
Servlet context path from the request path before performing path
matching with PathPattern instances.
This resulted in requests not matching as expected if the application
was configured with a Servlet context path.
This commit ensures that the `RequestPath` "path whithin the
application" is used for matching against path patterns.
Fixes gh-26411
