feat: optionally apply github-build-setup steps to additional jobs

[arusahni]

For some use cases, such as using private git crate dependencies in a project's Cargo.toml manifest, Github Actions requires a certain amount of ceremony to alias the private repo's Git URL to to something that can be cloned using an access token. For the build-local-artifacts job, this can be accomplished by adding the authentication step in the github-build-setup YML file.

There are additional jobs that necessitate these credentials be set, mainly the plan, build-global-artifacts, and host. This appears to be due to the fact they invoke cargo metadata (which attempts to resolve dependencies).

Support these use-cases by introducing a github-build-setup-jobs collection which allows users to opt-in to including the github-build-setup steps in various jobs.

Fixes #2065

Thanks for the submission!

This makes sense, and I understand the motivation, but I'm not sure always applying this is the best solution. The original motivation for this feature was to install package dependencies for builds - for example, a user needed to fetch a custom copy of Lua. This is a bit too heavy to apply to all steps if it's only neeed for builds; it would significantly add to the time it takes to run the full action without any benefit.

How about adding a new setting where we configure what phases to add the github-build-setup code to? It would default to local-build but could be extended to list other phases too, like what you're hoping for.

@mistydemeo that suggestion makes sense to me. Happy to make those changes.
