Vincent Ambo 0779f96687 feat(nix/buildkite): Check target map of parent to determine skips
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.
