sample_ext_app tests fail, NMR Attach failure.

### Describe the bug

sample_ext_app.exe fails to load programs. It looks like the sample-ext program type doesn't have a registered NMR provider to match with, even though it's a valid guid in [ebpf_program_attach_type_guids.h](https://github.com/microsoft/ebpf-for-windows/blob/main/include/ebpf_program_attach_type_guids.h).
