Keiichi Watanabe 901cd7df7f Reland "github: Minimize dependencies for document generation"
This is a reland of commit 2b85d4d1e5

Diff from the original CL:
* Changed the return value of `main()` in power_monitor/build.rs
* Ran cargo-check with all features enabled

Original change's description:
> github: Minimize dependencies for document generation
>
> Instead of install full dependencies with `install-deps` in GitHub
> action, minimize dependencies because we use GitHub only for document
> generation.
>
> - Passed `CARGO_DOC` environment when running cargo-doc command so we
>   can skip unnecessary build flow when we just want to generate API docs.
> - Added a new script `install-docs-deps` to install only doc-related
>   dependencies.
>
> BUG=none
> TEST=test on GitHub Action at my personal repository
