[lldb][test] Fix bf16 test cases on Arm 32-bit (#161528)

Fixes #157674

On ARM, the presence of a specific bf16 type in the AST is gated by: 
```
bool ARMTargetInfo::hasBFloat16Type() const {
  // The __bf16 type is generally available so long as we have any fp registers.
  return HasBFloat16 || (FPU && !SoftFloat);
}
```

And the target we use when evaluating symbols (derived from the program
file, I think, haven't found it yet) does not enable any of this.

This means that we fall back to __fp16.

So for parts of the testing we just need to expect __fp16 instead, and
others we need to skip because now a class looks like it inherits from
itself.

There's a proper fix here somewhere but I don't know what it is yet.
