Don't open a second Display, we can use the one used by Qt.
Advantages are: we are on the correct Display, we don't open a Display
connection on e.g. Wayland (it would succeed but not work as a connection
to Xwayland would be opened) and we can drop the copy of fixx11h.
It's also a prerequisite to properly split the implementation to support
Wayland in a later change.

Uses KPluginLoader+KPluginMetadata instead.
Describes plugins in json instead of desktop files. These desktop files are
then embedded into the .so file. All the plugins will be in a kdeconnect/
directory, and those will be the ones to look for.
Note it doesn't drop the KService dependency as KIOCore is a KDE Connect
dependency as well.

This meant to add a lot of dependencies to each plugin since we had
KDELibs4support as PUBLIC link meaning that anything linking against
kdeconnectcore was linking at the same time to mostly all frameworks.
Now each plugin has more or less its dependencies in the CMake some
still depend on KDELibs4Support.
For the mousepad plugin I needed to add a fixX11.h file that basically
undefines/defines again some stuff xlib has that conflcits with normal
C++ and Qt.
Before it was not conflicting because some lib within KDELibs4Support
was including this file, but now we have to do it ourselves.
I've also removed modifiers like Shift and Ctrl by now.
LibFakeKey is now a dependency of this plugin, as it allows us to send UTF
characters as X11 keys in a simple and convenient way. Internally it uses a
convention in Xlib, that allows to pass UTF characters as keycodes just by
adding 0x01000000 to the keycode number.
