Add AssumedSystemRequirementsInfo provider and lobster config

Extend the requirements rule to support assumed system requirements:

- Add AssumedSystemRequirementsInfo provider in providers.bzl
- Add 'assumed_system' to req_kind values in _requirements rule
- Add elif/else branch in _requirements_impl to return the new provider
- Add lobster config (lobster_assumed_system_req.yaml) and BUILD target
  for assumed system requirement traceability extraction
