rust: Emit toc files for cdylibs
Write toc files that list the exported symbols so dependents are
only rebuilt if the exported symbols change.
This exports the CC function TransformSharedObjectToToc, and also
removes an unused arg from its signature.
Bug: 178185435
Test: New Soong test passes.
Test: m <toc file path>
