This update refactors the Dawn backend to interface with a current external Dawn build using the monolithic 'webgpu_dawn' shared library and 'webgpu_cpp.h'. This is a large refactor of `engine_dawn.cc` which was AI-assisted, so it has mostly been reviewed for reasonableness and successful building and testing. It's intened to be better than it was, but still very much a WIP unstable backend. It's not clear which integration tests used to pass with the Dawn backend (since it has not been able to build for some time), but following this change at least 46 integration tests pass with the Dawn backend, so it is an improvement.
