Add support for customizing WebJars resource handler path pattern

Browse Source 
At present, both Spring MVC and Spring WebFlux auto-configurations
hardcode the path pattern for WebJars resource handlers to
"/webjars/**", which means users are unable to change the path.

This commit introduces "spring.mvc.webjars-path-pattern" and
"spring.webflux.webjars-path-pattern" configuration properties that
allow customization of WebJars resource handler path pattern.

The path can be customized with the configprop:spring.webflux.webjars-path-pattern[] property.
TIP: Spring WebFlux applications do not strictly depend on the servlet API, so they cannot be deployed as war files and do not use the `src/main/webapp` directory.

Although this directory is a common standard, it works *only* with war packaging, and it is silently ignored by most build tools if you generate a jar.
