rust: Support for generated c files from bindgen
To handle static inline functions, bindgen generates a C file which is
expected to be compiled and linked into dependents on the generated
bindgen source.
This CL adds support for cc modules ingesting this output and for
bindgen to produce it (and link it against the bindgen rust_library
variant as well).
Bug: 290347127
Test: m blueprint_tests
Test: Example module with static inline functions builds locally
