Upcoming Qt Wayland changes

[David Edmundson]

Starting with Qt6.10 the Qt wayland QPA (platform backend) will move
from the repository qtwayland to qtbase where all other platform
backends live.

QtWayland will continue to exist and as a repository and part of the
release, but will contain only parts needed to run the Qt Wayland
compositor. Which is a toolkit for making a compositor, and generally
not needed by applications or KDE.

One exception to this is the libadwaita gnome style decoration for
client side decorations required to work round Gnome that will
continue to live in QtWayland due to a dependency on QtSVG.

The other change to be aware of is QtBase will install some additional
development files needed for QtWayland to be able to build standalone.

If anything sounds like it will be a problem for your distribution
please let me know as soon as possible either here or on Qt's Jira.

Thanks
