configure -list-features does not list all wayland features

Running "configure.bat -list-features" produces only two switchable features for qtwayland, even though they are in the source tree.

[t_kyzik@localhost bld]$ ../configure -list-features 2>&1 | grep wayland
wayland-compositor-quick . Allows QtWayland compositor types to be used with QtQuick
wayland-text-input-v4-wip  Enables wayland_text_input_unstable_v4(wip)

I checked to see if the kind of fix for QTBUG-96196 was applicable to this situation, and it appears not. There is a qt_cmdline.cmake which lists the directories in which features are defined, and putting a NOT QT_CONFIGURE_RUNNING guard around the qt_find_package calls didn't seem to help.

It would be very nice to be able to show that you can turn off the wayland server support.
