This simplifies the fallback logic used in case of Nix evaluation
failure and makes it so that the evaluation step itself is the one
that is marked as failed in Buildkite.
This is possible because the pipeline upload command will insert new
steps at the point where it runs in the pipeline, and not later.

Instead of manually tracking the build status through Buildkite
metadata, use the Buildkite GraphQL API in the `🦆` build
step (i.e. the one that determines the status of the entire pipeline
to be reported back to Gerrit) to fetch the number of failed jobs.
This way we have less manual state accounting in the pipeline.
The downside is that the GraphQL query embedded here is a little hard
to read.
Notes:
* This needs an access token for Buildkite. We already have one for
besadii which is also run by the agents, so I've given it GraphQL
permissions and reused it.
* I almost introduced a very rare bug here: My initial intuition was
to simply `exit $FAILED_JOBS` - in the extremely rare case where
`$FAILED_JOBS % 256 = 0` this would mean we would ... fail to fail
the build :)

It seems that shell variables don't work as expected inside the
Buildkite pipeline, so usage of variables has been removed.
We also don't echo the revision anymore because of that, but it does
still appear in the log of `git push`.

This makes the revision number available much earlier (before the rest
of the pipeline runs, while Nix eval is happening) which should only
be a few seconds after a commit to canon.
It is also more readable in this shape.

We changed the configured pipeline in Buildkite to upload
`static-pipeline.yaml` instead of containing the steps of that
pipeline itself.
This makes it easier to test changes to builds and such, but adds
another build step with scheduling overhead etc.
However - we can work around this by killing one of the existing build
steps. There's no reason the failure status zeroing (required for
status reporting) shouldn't be part of the pipeline setup, so I've
moved it there instead and nuked that step.
This should mean that the pipeline is configurable from within the
repo, but without slowing anything down.

This file represents the static pipeline which is configured in the
Buildkite web UI. Updates to this file should be applied in the admin
interface.
These steps are responsible for launching the dynamic pipeline
evaluation, or falling back to the fallback pipeline if evaluation fails.
