Subject: [PATCH] clang-tidy: Disable `UndefinedBinaryOperatorResult` check in
 `src/ipc`

The warnings are false positive and have been fixed upstream.
See: https://github.com/capnproto/capnproto/pull/2334.

This change disables the `UndefinedBinaryOperatorResult` clang-tidy
check for source files generated by the `mpgen` tool.
