Deprecate UrlPathHelper shortcuts on AbstractHandlerMapping

Given the availability of two alternatives mechanisms for URL path
matching, PathPatternParser and AntPathMatcher, and now that
parsed patterns are enabled by default, it makes sense to reduce the
proliferation of options on AbstractHandlerMapping by deprecating
shortcuts related to String path matching. Most applications rely
on Boot and on the MVC config to do all this.
