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.
