xwayland-satellite v0.7

A smaller release, with mostly internal facing (but big) changes. Here are the most interesting ones:

-listenfd support

Compositors that wish to integrate satellite similarly to those that build in Xwayland support natively can do so thanks to the now supported -listenfd flag. Check the readme for information on how this can be used. This is already in use in the latest commit for Niri for autostarting satellite, and will be enabled by default in the next Niri release. Thanks to @YaLTeR for the implementation.

ECS refactor

Satellite now uses the hecs ECS for managing Wayland objects. This should not have any user facing effect, but makes development a little easier.

Clipboard test stabilization

Thanks to @En-En-Code's hard work, clipboard tests have now been stabilized. This should help stabilize the CI.
