Handle TESTDATA for Qt Tests

These changes enable the support to handle test data and install or
package them as resources when appropriate.

This change does not handle the GENERATED_TESTDATA or
TEST_HELPER_INSTALLS since there are very few occurrences of these and
we can handle those as special cases.

Finally, in add_qt_test, only append CMAKE_CURRENT_SOURCE_DIR if
the path is not absolute.
