CMake: Split target finalization code into a separate function

Browse Source 
It was duplicated across a few public API.
Splitting it will also allow it to be be reused in a future change
in another function.

Also add the ability to use the poor man finalizer approach for
CMake 3.16, but only via an opt-in that will be set by the qt build
process, so that the finalizers can be used for tests in a future
change.
