QtVirtualKeyboard on Plasma Wayland

[David Edmundson]

For anyone else testing:
 - you need to set KWIN_IM_SHOW_ALWAYS=1 or have a touchscreen (or mod kwin)
 - you need the right hunspell dictionary installed or it just doesn't
send anything

It kinda feels we've gone full circle, Kwin used to do the Qt VK in process.

It's too early to say anything for definite but I do think it's a good
direction to explore.
Maliit doesn't seem very alive whereas Qt VK somewhat is and the way
you've split this we are in full control of bridging any wayland
oddities which is a win-win.
