Fix a bug introduced by 2ca153141 (I merged the wrong patchset).
Issue happens when pipeline is split by phases into independent
evals (e.g. build/release/deploy).
Splitting extra steps requires knowledge of all known phases,
otherwise pipeline evaluation fails due to extra steps from inactive
phases.

This change automatically extends the list of known phases as soon as
they are added to active phase list.
This is great when a user wants to design pipelines with multiple
groups of dynamic steps.
For example in Resoptima we want to design deployment pipeline where
first only staging k8s namespaces are updated/tested and only after,
we update production.

We found a bug after updating to latest tvl-kit which broke
incremental releases.
Bug was related to the fact that extra steps skip attribute had
precedence over parent configuration. This is a desired behavior when
extra step is explicitly set to `skip=true` but otherwise it must
follow parent.
Due to extra step normalization skip parameter is always set to false
if not explicitly set.
Along the way, I'm adding support for setting skip attribute on extra
steps as string so that people can define skip reasons.
The bug was introduced by commit:
b9d79109d feat(ops/buildkite): Allow skip of individual steps

Upstream nixpkgs removed a lot of aliases this time, so we needed to do
the following transformations. It's a real shame that aliases only
really become discoverable easily when they are removed.
* runCommandNoCC -> runCommand
* gmailieer -> lieer
We also need to work around the fact that home-manager hasn't catched
on to this rename.
* mysql -> mariadb
* pkgconfig -> pkg-config
This also affects our Nix fork which needs to be bumped.
* prometheus_client -> prometheus-client
* rxvt_unicode -> rxvt-unicode-unwrapped
* nix-review -> nixpkgs-review
* oauth2_proxy -> oauth2-proxy
Additionally, some Go-related builders decided to drop support for
passing the sha256 hash in directly, so we need to use the generic hash
arguments.

This is supposed to help with resource wasting in situations when
multiple dynamic steps depend on a failing derivation. Cost of
failure currently is `C = T * D` where:
- T -> time to compile the failing derivation
- D -> amount of CI targets depending on a failing derivation
Switching to `Fail Fast` limits it to just T (time of a single
failure). Which helps a lot, especially while upgrading nixpkgs.
Fast fail at this moment is in preview, so to enable it:
- Enable `Fail Fast` feature at pipeline or organization level
- Set `cancelOnBuildFailing` parameter to true for `mkPipeline`

Generating a release-only pipeline skips a bigger chunk of eval this
way (the step itself is never actually evaluated, which means we never
actually compute the drv), which can be quite beneficial in terms of

Previously the extra steps were roughly divided into steps that run
"at build time" (i.e. before we publish results to Gerrit), and
"post-build" (i.e. later on).
In practice, these are something like a build/release pairing, where
steps running after the build results are returned are mostly run for
side-effects (e.g. publishing git subtrees to external repos).
This refactoring makes this distinction explicit in //nix/buildkite
and changes the extraSteps API with an explicit `phases` attribute
instead of the previous `postStep` attribute.
In practice the previous API is still supported, but will throw
evaluation warnings until an arbitrarily chosen cutoff date of
2022-10-01 at which point we will change using it into a hard error.
This uncovered a few strange behaviours which we only accidentally
avoided, most of which I have left TODOs about and will clean up in
subsequent commits.
The purpose of this commit is to allow for separate evaluations of
only build or only release steps, for example if release steps are
evaluated in a slightly different context (e.g. with overridden
versioning that is not relevant to standard CI functionality).

This was useful to have in CI, e.g. when targeting a specific NixOS
system. The actual result symlink which is printed is not useful.
Alternative solution would be to change the wrapping of this so that
we conditionally create the symlink for extra steps, but I think it's
not worth the complexity of evaluating the step twice.

The previous `condition` abstraction which allowed the full set of
Buildkite conditionals is way too leaky (it lets users to very
Buildkite-specific things which we may not want to allow, and which
are mostly not relevant to a pure evaluation).
Supporting only the `branches` condition (native to Buildkite) should
make it possible to port this to other future CI systems later.

This changes the logic for build pipeline generation to inspect
an (optional) parentTargetMap attribute which contains the derivation
map of a target commit.
Targets that existed in a parent commit with the same drv hash will be
skipped, as they are not considered to have changed.
This does not yet wire up any logic for retrieving the target map from
storage, meaning that at this commit all targets are always built.
The intention is that we will have logic to fetch the target
map (initially from Buildkite artefact storage), which we then pass to
the depot via externalArgs when actually generating the pipeline.

Always create a structure that maps all targets to derivations, and
persist it as a JSON file.
This relates to some of the ideas expressed in:
https://docs.google.com/document/d/16A0a5oUxH1VoiSM8hyFyLW0WiUYpNo2e2D6FTW4BlH8/edit
The file is always uploaded to Buildkite as an artifact. This allows
for retrieving it based on the commit ID in a Buildkite GraphQL query.
By default, Buildkite stores artefacts for 6 months. Storage location
can be overridden (with custom retention) through some environment
variables, but for now at TVL the Buildkite-managed storage is fine.
See also: https://buildkite.com/docs/pipelines/artifacts
In the subsequent filtering implementation, when diffing commits
across a time-range that exceeds artefact retention time, we should
simply default to building everything.
