patrick96 c24a6999a4 refactor(cmake): Allow targets to be enabled individually
Each major target of polybar can now be enabled/disabled while
configuring (even polybar itself).

The cmake code specific to each target will only run if the target is
enabled.

This allows us to for example just build the documentation without
having to run all the cmake code related to compilation or having the
polybar dependencies installed (other than sphinx).
