We don't need to calculate dependencies between and on targets that are
part of the parent target map since they will be skipped by buildkite
anyways. This speeds up 🦙 considerably for pipeline runs that have a
limited number of changed targets and a parent target map passed
in (i.e. pipeline runs of most CLs, but not canon runs). In my testing
it was about a minute faster (1/6 of the time 🦙 takes currently) for a
pipeline where under five drv targets changed. For the full
pipeline (i.e. no parentTargetMap) 🦙 takes about the same time as
before (it's a few seconds slower as is to be expected, but nothing
significant).
