Description

When I try to add a bridging header with `swift_copts = ["-import-objc-header", "path/to/Bridging-Header.h"]`, it fails to build, telling me that frameworks don't support bridging headers. Ideally, this wouldn't happen, and also there'd be a `bridging_header` attr or something

Research direction

Start by reproducing the build failure with `swift_copts = ["-import-objc-header", "path/to/Bridging-Header.h"]` and inspect the framework handling that rejects bridging headers. The work is done when bridging headers are supported or a `bridging_header` attribute provides equivalent configuration, with coverage for the reported setup.
