tpl_display: Added a new API to get existed display with backend type.

 - Added API below.

    Get TPL display object for the given native display.

 If there's already existing TPL display for the given native display and backend type,
 then return the existed TPL display object.

 If the given backend type is TPL_BACKEND_UNKNWON,
 it behaves the same as tpl_display_get().
 Otherwise, it searches for the tpl_display created with the given type.

 @param type backend type of the given native display.
 @param native_dpy handle to the native display.
 @return pointer to the display on success, NULL on failure.

   tpl_display_t *
   tpl_display_get_with_backend_type(tpl_backend_type_t type,
				     tpl_handle_t native_dpy);
