[LLDB][PDB] Run UDT layout test with native PDB too (#159769)

This test was failing with the native plugin due to two reasons:

1. The static `C::abc` was printed as `(int) ::C::abc = 123`
2. The order of the base classes of [`C`
(`List::Value`)](https://github.com/llvm/llvm-project/blob/b7e4edca3d56ec87f719c202f5397b245595f7cc/lldb/test/Shell/SymbolFile/PDB/Inputs/UdtLayoutTest.cpp#L30)
is different between DIA and the native plugin. I don't know how the
order in the DIA plugin is determined - it prints `B<0>`, `B<1>`,
`B<2>`, `B<3>`, `A`. The native plugin follows the order of the bases in
memory and prints `B<2>`, `B<3>`, `A`, `B<0>`, `B<1>` (last three are
the virtual bases).

    ```
    </details>

I split the tests for the plugins for better readability.
