    Make eglot--plist-keys a simple (non-map.el) helper again
    
    This removes a nagging compilation warning when developing on Emacs
    master.
    
    There's not much point in depending on map.el just for this util.  And
    there' snot much point in making eglot--plist-keys go through a
    generic dispatching mechanism when we happen to know the thing
    being dispatched
    
    * eglot.el (eglot--plist-keys): Define in helpers section.
