Migrate remaining SpecialSeedGenerators to SeedingLayerSetsHits

[makortel]

Migrate SpecialSeedGenerators still using SeedingLayerSetsBuilder to use SeedingLayerSetsHits. These generators are

• BeamHaloPairGenerator
• GenericPairGenerator
• GenericTripletGenerator
• SimpleCosmicBONSeeder

The migration allows removal of TrackingRegion::hits(..., const ctfseeding::SeedingLayer*) method since nobody calls it anymore, simplifying the TrackingRecHit rework.

There should be no effect on physics.
