temp/plasma-phone-components-vkbd-style: new aport

Bring it back, until we can depend on another keyboard in
postmarketos-ondev. I considered switching to maliit or squeekboard, but
both are not that trivial so let's investigate that another time.

- Maliit uses a whole different mechanism than this
  qtvirtualkeyboard-style (we'd need to start a minimal plasma-workspace
  environment or however ubports does it?).

- squeekboard requires running a wayland compositor like phoc or sway.
  These would need some additional packaging to run on phones that still
  rely on framebuffer, and besides that it seems unlikely that the
  qtvirtualkeyboard hints like "use only numbers here", "start with
  lowercase letter" etc. as used by the installer would work as expected
  with squeekboard (not tested).
