Cache CI Docker images in ghcr registry This PR changes the way `rust-lang` caches Docker images used in CI workflows. Before, the intermediate Docker layers were manually exported from `docker history` and backed up in S3. However, this approach doesn't work any more with the Docker version used by GitHub Actions since August 2023. We had to revert to disabling Docker BuildKit to make the old caching work, but this workaround will stop working eventually, after GitHub updates Docker again and the old build backend will be removed. This PR changes the caching to use [Docker caching](https://docs.docker.com/build/cache/) instead. There are several backends for the cache, for our use-case S3 and Docker registry makes sense. This PR uses the Docker registry backend and uses the ghcr.io registry. The caching creates a Docker image labeled `rust-ci`, which is currently stored to the `ghcr.io/rust-lang-ci` package registry. This image appears [here](https://ghcr.io/rust-lang-ci/rust-ci). The image is stored in `rust-lang-ci` and not `rust-lang`, because `try` and `auto` builds run in the context of that repository, so the used `GITHUB_TOKEN` has permissions for it (unlike for `rust-lang`). For pull request CI runs, the provided `GITHUB_TOKEN` reduces its permissions automatically to `packages: read`, which means that we won't be able to write the Docker image. If we're not able to write, we won't have anything to read. So I disabled the caching entirely for PR runs (it makes it slightly faster to build the Docker image if we don't have to deal with exporting and using a separate build driver). Note that before this PR, we also weren't able to read or write the cache on PR runs. Rustup part of this change is [here](https://github.com/rust-lang/rustup/pull/3648).
