CI: Replace deprecated/unmaintained actions-rs with simple `run: st…

…eps`

The `actions-rs` containers haven't been maintained and updated for
years and don't need to: GitHub's actions environment already comes
fully loaded with a complete `stable` Rust installation with the
standard tools (clippy, rustfmt, rustdoc).  Simple `run:` commands
relate directly to what a developer can type in locally to "reproduce"
the CI environment while they might be following up on CI failures, and
no longer spam ancient Node 12 deprecation warnings.
Whenever a different toolchain or additional targets are needed,
https://github.com/dtolnay/rust-toolchain is used to install it instead.

The only downside is that `actions-rs/clippy-check` properly embeds
build failures as code annotations in the diff; but as shown in e.g.
https://github.com/Smithay/drm-rs/actions/runs/11632990715/job/32397210203
this doesn't even work for PRs from forks.
