CMake: Replace qt_finalize_executable with qt_finalize_target

It's very likely that we'll have to run certain finalizer code for
targets other than executables.

Rename qt_finalize_executable to _qt_internal_finalize_executable so
it's internal.

Introduce a new function qt_finalize_target which will call the above
internal one when the target is an executable.

This should future proof the API so we have a hook to call code for
any user CMake project that intends to use Qt CMake API.
