bitbake: bitbake: tests/data: add tests for variable flags

Check default flags are correctly returned by getVarFlags and check all flags
are returned when internalflags is True.

Check delVarFlags also removes default value.

Check all flags are removed after delVar.

Run the test with:
    $ bitbake-selftest -v bb.tests.data.TestFlags
    test_delflag (bb.tests.data.TestFlags.test_delflag) ... ok
    test_delvar (bb.tests.data.TestFlags.test_delvar) ... ok
    test_setflag (bb.tests.data.TestFlags.test_setflag) ... ok

    ----------------------------------------------------------------------
    Ran 3 tests in 0.000s

    OK

This is a test case for [YOCTO #15685]
