Add support for injecting recently introduced (Linux) NetDevices to OCI Specs. Once all the necessary bits are merged and make their way to the runtimes, merging this should allow injection of (Linux) NetDevices over CRI without any changes to the protocol.

Notes:
This PR is marked a draft since it uses an untagged opencontainers/runtime-spec version v1.2.2-0.20250401095657-e935f995dd67. Once a new version is tagged, we can mark this PR ready for review.

Yes, I am planning to do it once the necessary runtime-spec bits get tagged.
