feat: move blueprint ab logic into sofie SOFIE-2403

[Julusian]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

feature

• What is the current behavior? (You can also link to an open issue here)

AB playback logic is 99% handled by blueprints in onTimelineGenerate. There are a couple of helper methods provided to deal with ids, the rest is left to blueprints to figure out themselves.

• What is the new behavior (if this is a feature change)?

All of this AB logic that blueprints used to have to implement, is now moved into the core of Sofie.
Blueprints can enable this AB logic by implementing the getAbResolverConfiguration method in the ShowStyle blueprint, which is where the pools are defined along with any rules on how to apply the player assignments to the timeline.

• Other information:

Q) Should abSession be defined on Piece or PieceGeneric? There are complications risen due to needing to handle AB from adlib pieces, so perhaps we could take a stance of not supporting it?

Status

• Code documentation for the relevant parts in the code have been added/updated by the PR author
• The functionality has been tested by the PR author
