feat(ops/pipelines): Add Buildkite pipeline configuration This adds configuration which generates the structure expected for Buildkite pipelines, which can then be dynamically ingested by Buildkite when a pipeline is triggered.

# This file configures the primary build pipeline used for the
# top-level list of depot targets.
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.

feat(ops/pipelines): Dynamically generate CI pipeline from targets Create the pipeline by outputting a file that contains nix-build invocations for each target's *derivation path*. Each invocation has a generated Nix expression passed to it with `-E` which fetches the correct target from the tree while correctly handling targets with strange characters (such as in Go-packages). This makes it possible to run target-level granular pipelines. We're getting somewhere!

feat(ops/pipelines): Create drvmap structure for each commit 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.
