[BUG] Wayland Unicode characters only working in some apps under nested kwin session

[thelamer]

Currently in wayland mode if kwin_wayland binary is detected we do not use the wtype fallback as that api is not available on kwin we try to inject the unicode chracters by dumping the raw hex and typing it out with the ctl+U standard keyboard macro via https://github.com/selkies-project/selkies/blob/main/src/selkies/input_handler.py#L1262-L1281, this only works on some applications. (web browsers and electron based seems to work along with GTK, QT has issues)

We need to find a better way to do this in Kwin as this effects both IME and some very standard é keys for European layouts.
