Implement error reporting for the bindings generator.
This feature aggregates nonfatal errors encountered while generating bindings and writes a JSON report to a file. It can be activated by passing `--//path/to/crubit/bazel_support:generate_error_report` to a Bazel build that generates bindings. The error report is named `${cc_library}_rust_api_error_report.json` and appears in the output directory alongside the generated bindings.
