[kwin] Adjust CMakeLists.txt to allow standalone built of KWin

Preparation step before splitting:
* adds project(KWIN)
* lists all KWin dependencies

KWin can be built standalone if cmake is run with:
-DKWIN_BUILD_OXYGEN=OFF
-DKWIN_BUILD_KAPPMENU=OFF

Oxygen because it needs liboxygen - for standalone clients/oxygen needs
to be moved out of KWin.

KAppmenu because it includes the DBus xml file.
