Target finalizers are not run for qt_internal_add_executable/app/tool

This is split from QTBUG-112212

Comment from above issue.

Running finalizers should now work for qt_internal_add_tests and friends executables.

They are still not run for qt_internal_add_executable, qt_internal_add_app, qt_internal_add_tool (EDIT: except for ANDROID and WASM where we do run them for any kind of internal executables).

That needs more work.
Part of the reasoning is described at https://codereview.qt-project.org/c/qt/qtbase/+/599348/10/cmake/QtExecutableHelpers.cmake#46

One of the issues is that trying to run finalizers for the qmlimportscanner executable (which is a tool) would create a circular depenendecy trying to run
qmlimportscanner on itself.
