[lldb][test] TestConstStaticIntegralMember.py: XFAIL on Darwin for older compiler verions

Follow-up to #111859. Prior
to this PR we would never run these tests with DWARFv5 on older Clang
versions (since default wasn't DWARFv5 on macOS until recently). The
patch explicitly started running some of these tests with DWARFv5.
These were failing on the macOS matrix bot (with Clang-15/Clang-17).
