Fork specification specific build-tools (protoc) into a specification-tools repository

[jsuereth]

Today the build-tools repository is an amalgamation of three major components:

• A docker image with C++ development tooling
• A docker image to validate the open-telemetry/opentelemetry-proto repository
• Tooling for semantic conventions.

Due to the split ownership model, no single group feels responsible and simple fixes like dependabot PRs have lagged in this repository.

I'd like to propose splitting out components with clear ownership. For the Specification this means taking ownership of the proto related tooling and having a single repository that would be maintained by Specification owners (in addition to the opentelemetry-proto repository).

@lquerel FYI, this might be a good opportunity to have a joint effort with Weaver.

Yep. I'm collaborating with @jsuereth on this topic.
