This builds yuzu in an AppImage alongside the other archives during
release. Required to allow distributing yuzu in the future with upgraded
dependencies, such as Qt.
Unicorn has been removed, yet CI still enables building with Unicorn.
This just cleans up a few leftovers by removing the variable from the
CMake parameters in CI.
yuzu's web applet does not or barely reacts to user input while open in
Linux. It can be closed via 'Exit Web Applet' on the menubar, however if
yuzu is in fullscreen, this is effectively a softlock as the menubar
cannot be accessed.
This disables building yuzu with the web applet on the Linux CI target.
In addition, this disables the QMessageBox warning about not having
compiled yuzu with the web applet.
This is possible now with the updated Docker images and their updated packages.
Before, there were build errors due to old QT5 packages on Ubuntu, but now since
they have updated packages it is feasible to build with Vulkan enabled once more.
We don't need to depend on a custom fork for this. We can add the
library as is, and then make it excluded from the ALL target, so we only
link in the libraries that we actually make use of.
