screen-cast-stream-src: Move FormatParam building code into function
To fixate the format or renegotiate after a DMABUF allocation failed we need to rebuild the EnumFormat params. The function meta_screen_cast_query_modifiers will return false if no modifiers are supported, thouse we can drop the check and remove the macro guard.
