[FrameworkBundle/Routing] Add "type" option for main Router resource (and expose this in FrameworkExtension config)

In routing files, import statements allow an optional "type" option to hint the resources' type (e.g. for ambiguous file extensions). This adds the same type option to the FrameworkExtension config, which defines the main routing resource.
