## Problem
We don't rebuild `build-tools` image for changes in a workflow that
builds this image itself
(`.github/workflows/build-build-tools-image.yml`) or in a workflow that
determines which tag to use
(`.github/workflows/check-build-tools-image.yml`)
## Summary of changes
- Use a hash of `Dockerfile.build-tools` and workflow files as a
persistent tag instead of using a commit sha.
## Problem
I've bumped `docker/setup-buildx-action` in #8042 because I wasn't able
to reproduce the issue from #7445.
But now the issue appears again in
https://github.com/neondatabase/neon/actions/runs/9514373620/job/26226626923?pr=8059
The steps to reproduce aren't clear, it required
`docker/setup-buildx-action@v3` and rebuilding the image without cache,
probably
## Summary of changes
- Downgrade `docker/setup-buildx-action@v3`
to `docker/setup-buildx-action@v2`
## Problem
We have some amount of outdated action in the CI pipeline, GitHub
complains about some of them.
## Summary of changes
- Update `actions/checkout@1` (a really old one) in
`vm-compute-node-image`
- Update `actions/checkout@3` in `build-build-tools-image`
- Update `docker/setup-buildx-action` in all workflows / jobs, it was
downgraded in https://github.com/neondatabase/neon/pull/7445, but it
it seems it works fine now
## Problem
We use ubuntu-latest as a default OS for running jobs. It can cause
problems due to instability, so we should use the LTS version of Ubuntu.
## Summary of changes
The image ubuntu-latest was changed with ubuntu-22.04 in workflows.

## Problem
Move from aws based arm64 runners to bare-metal based
## Summary of changes
Changes in GitHub action workflows where `runs-on: arm64` used. More
parallelism added, build time for `neon with extra platform builds`
workflow reduced from 45m to 25m
## Problem
`build-build-tools-image` workflow is designed to be run only in one
example per the whole repository. Currently, the job gets cancelled if a
newer one is scheduled, here's an example:
https://github.com/neondatabase/neon/actions/runs/8419610607
## Summary of changes
- Explicitly set `cancel-in-progress: false` for all jobs that aren't
supposed to be cancelled
## Problem
Currently, after updating `Dockerfile.build-tools` in a PR, it requires
a manual action to make it `pinned`, i.e., the default for everyone. It
also makes all opened PRs use such images (even created in the PR and
without such changes).
This PR overhauls the way we build and use `build-tools` image (and uses
the image from Docker Hub).
## Summary of changes
- The `neondatabase/build-tools` image gets tagged with the latest
commit sha for the `Dockerfile.build-tools` file
- Each PR calculates the tag for `neondatabase/build-tools`, tries to
pull it, and rebuilds the image with such tag if it doesn't exist.
- Use `neondatabase/build-tools` as a default image
- When running on `main` branch — create a `pinned` tag and push it to
ECR
- Use `concurrency` to ensure we don't build `build-tools` image for the
same commit in parallel from different PRs
