data-device: allow multiple devices for the same seat

This commit makes it possible for a single client to have multiple data devices
for the same seat. This fixes issues with Firefox.

This mainly removes wlr_data_source.offer. We make sure we create one data
offer per device. We now make the offer inert when the source is destroyed.

Fixes the second half of https://github.com/swaywm/wlroots/issues/1041
