Handle test helpers better

Teach pro2cmake to use add_qt_test_helper instead of
add_qt_executable when the qmake 'qt_test_helper' feature is used.

Don't use macOS bundles when building tests on macOS, because that
breaks path assumptions for certain tests.

Introduce a new OVERRIDE_OUTPUT_DIRECTORY option for add_qt_test_helper
that allows placing the binary into a folder other than the test parent
folder. I considered changing the default behavior not to place into the
parent folder, but that would break all existing tests, so I opted for
override approach instead. Ultimately we might want to revisit this
later.
