Clean WebSocketSharpRequest.PathInfo (#1212)

* rm useless ResolvePathInfoFromMappedPath method

* rm useless NormalizePathInfo method

* Use request.Path instead of RawUrl

* Removing unused `HandlerFactoryPath` field

* Use an  expression body definition and rm field `pathInfo`

* More (syntactic) sugar

* Who needs blocks in cases ?
