Squashed commits for Pseudotracking migration to CA
Unfudged-MR (hopefully...???) of !52764 (closed)
Migrated Pseudotracking to using CA by adding a TruthTrackingConfig to run it.
New flags InDet.Tracking.doPseudoTracking
and InDet.Tracking.doIdealPseudoTracking
.
CA now reproduces the OLD config results and this MR is ready for review.
