tdf#125922 rename kde5 to kf5 + plasma5

Just as the gtk3 plugin isn't named GNOME, rename kde5 to kf5, as
it is based on the KDE frameworks 5 libraries.

This also includes:
* a convenience alias to load the kf5 VCL plugin in case someone
  requests the kde5 plugin.
* keep convenience kde5 configure switch, but warn about it
* rename detected desktop from kde5 to plasma5
