selftests/bpf: Add tests for bpf_dynptr_copy
Add XDP setup type for dynptr tests, enabling testing for
non-contiguous buffer.
Add 2 tests:
- test_dynptr_copy - verify correctness for the fast (contiguous
buffer) code path.
- test_dynptr_copy_xdp - verifies code paths that handle
non-contiguous buffer.
