gtk-primary-selection: support multiple devices 

When a client was creating multiple data devices for the same seat, we were
only creating one resource. This is a protocol error.

Instead, create one offer per data device.

This commit also makes offers inert when their source is destroyed.

Fixes part of https://github.com/swaywm/wlroots/issues/1041
Supersedes https://github.com/swaywm/wlroots/pull/1113
