Add more vendored protos that we plan to use in the future. This reorganizes all of the .proto files so that they are in a single src/protos folder and are generated into a single protos.{d.ts,js} file. The protos themselves are namespaced so that the individual namespaces are still imported from the single "protos" module, as needed.

The documentation is generated from this commit.

Stub out the Starlark debugger client. This commit adds a menu item to debug a build, which starts the VS Code debug client and then launches Bazel inside it, but otherwise does not yet manage any debugging state (like breakpoints or frames).
