Provide generated proto files for go

[evan-gray]

Expected Behavior

As a go integrator, I shouldn't have to generate the proto libraries from source.

Current Behavior

Integrators using go must pull the protos and generate the libraries from source in order to depend on anything in node or cleanly hit the gRPC endpoints. Guardians /

Possible Solution

Commit the generated proto files and add a CI step to ensure the committed files match a fresh build from the same commit (to keep them in sync).

Context (Environment)

Building an indexer for the wormhole ecosystem.
