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 Change-Id: I167a8356eb6e0059fc21169fd3bfc6bf4d9c812f
