meson: Add more qt options and eliminate all automagic
The qt5 and qt6 plugins will now correctly error out if you enable the option, and you can also now explicitly ensure that wayland, x11, eglfs support is actually functional by enabling the options. It was too easy to build non-functional support for these. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4776>
