This splits the building of docker images in 2 jobs, one for each
platform, using the native ARM runners for arm64.
The tricky part here is to get back a nice multi-arch manifest.
Previously, you'd do that by pushing each platform image in two distinct
tags, then referencing them in a multi-arch manifest. Nowadays, it's
possible to push images by their digest only, then creating the manifest
for those pushed digests separately
This is inspired by the Docker docs on how to distribute multi-platform
image builds:
https://docs.docker.com/build/ci/github-actions/multi-platform/#distribute-build-across-multiple-runners
`ghcr.io/element-hq/synapse:sha-c733dd6` is an example image that got
built by this workflow (there is a temporary sha-* tag on
workflow_dispatch runs to help trying out the workflow)
I also had to make sure we sign the manifests correctly:
```
$ cosign verify --certificate-oidc-issuer https://token.actions.githubusercontent.com --certificate-identity-regexp 'https://github.com/element-hq/synapse/.github/workflows/docker.yml@.*' ghcr.io/element-hq/synapse:sha-c733dd6
Verification for ghcr.io/element-hq/synapse:sha-c733dd6 --
The following checks were performed on each of these signatures:
- The cosign claims were validated
- Existence of the claims in the transparency log was verified offline
- The code-signing certificate was verified using trusted certificate authority certificates
```
And the numbers aaaaare 🥁

After the [recent supply chain attack](https://www.wiz.io/blog/new-github-action-supply-chain-attack-reviewdog-action-setup)
in `tj-actions/changed-files` and actions based on it, it's become clear
that relying on git tags to pin our dependencies is not enough (as tags
can simply be replaced). Therefore we need to switch to hashes.
Dependabot should continue to update these dependencies for us.
Best reviewed commit-by-commit. Though if CI passes, we're *probably*
fine.

Update the "Build docker images" GitHub Actions workflow to use
`docker/metadata-action` to generate docker image tags, instead of a
custom shell script.

PyNaCl's recent 1.5.0 release on PyPi includes arm64 wheels, which means our
arm64 docker images now build in a sensible amount of time, so we can skip the
amd64-only build.
