[roll pigweed] pw_web_ui: Move building protos to a node script and add log.proto

We want to bundle log.proto so users can use pw_log_rpc without
having to rebuild protocollection themselves.

This also cleans up package.json and moves list of protos to a node
script which also resolves import issues with log.proto file.
