tst_qlocale: Add tests for parsing Chakma date and time strings

Add tests to verify parser behavior with locales that use code points
outside of Unicode BMP to represent dates. ccp is used for this because
Chakma language uses code points outside of BMP for both letters and
digits. QDateTimeParser currently is not able to handle this locale
correctly, so the tests are marked as expected failures.
