gpu: nova-core: emit Rust metadata for nova-drm

Browse Source 
Emit nova-core's crate metadata (libnova_core.rmeta) so that nova-drm
can import nova-core's types and functions at compile time.

This is intended to be a workaround until the build system supports Rust
cross-crate dependencies natively.
