🍒 [lldb] Fix TestRealDefinition on older DWARF versions (#165729)

Browse Source 
Cherry-picks this fix from the Apple LLDB fork. Ever since we upstreamed
https://github.com/llvm/llvm-project/pull/164011, this test is failing
on our pre-DWARFv5 bots:

Original commit message:

For a while, tests were run with `target.prefer-dynamic-value`
overridden to `no-dynamic-values` – but the override was removed in
[D132382](https://reviews.llvm.org/D132382). At that time, tests that
failed were individually opted in to `no-dynamic-values`.

I don't recall specifics about `TestRealDefinition`, but it currently
fails with `no-dynamic-values`, and that is correct behavior. This
change removes the `no-dynamic-values` override.
