ci: enable multiarch builds

[strophy]

Issue being fixed or feature implemented

We need to support arm64 architecture for devs and running devnets. This PR enables multiarch builds in CI.

What was done?

Upstream images we depend on to build for each arch do not yet support arm64. Some projects are abandoned and no longer build. This PR rebases the images on which we depend to maintained forks, and PRs have been opened here, here and here to update the supported projects, and here and here to update our own components.. Until all of these projects have updated, we can use manually built images with multiarch support: strophy/grpc-web-common (source) and strophy/protoc (source). Let me know if you want to move these images under the dashpay org.

How Has This Been Tested?

In CI
