data-device, primary-selection: add request_set_selection
This makes compositors able to block and/or customize set_selection requests coming from clients. For instance, it's possible for a compositor to disable rich selection content (by removing all MIME types except text/plain). This commit implements the design proposed in [1]. Two new events are added to wlr_seat: request_set_selection and request_set_primary_selection. Compositors need to listen to these events and either destroy the source or effectively set the selection. Fixes https://github.com/swaywm/wlroots/issues/1138 [1]: https://github.com/swaywm/wlroots/issues/1367#issuecomment-442403454
