Provide a kernel API to retrieve secrets from the UV secret store.
Add two new functions:
* `uv_get_secret_metadata` - get metadata for a given secret identifier
* `uv_retrieve_secret` - get the secret value for the secret index
With those two functions one can extract the secret for a given secret
id, if the secret is retrievable.

Is 32 skipped intentionally? Should there be a comment here that it is reserved?
