cmTestGenerator: Evaluate generator expressions in test properties

This is useful for cases like:

  add_test(NAME mytest COMMAND mydriver $<TARGET_FILE:myexe>)
  set_tests_properties(mytest PROPERTIES
    REQUIRED_FILES "$<TARGET_FILE:myexe>"
    WORKING_DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}/$<CONFIGURATION>"
    )

In this example we require the actual test executable to exist to
run the test in addition to the test driver at argv[0].  Also the
$<CONFIGURATION> expression improves over \${CTEST_CONFIGURATION_TYPE}
because the latter is not normalized for case-sensitive filesystems.
