Make print() work from starlark transition implementation functions.
Give each starlark transition a stored event handler. After starlark transitions are applied (after top level transitions and inside configuration resolver), replay and then clear events.
Declare a new abstract class for starlark transitions to consolidate fields/behavior.
Add behavior to ComposingTransitions to allow decomposition. This is helpful here but will also be helpful in future work where we'll need to post-process starlark transitions after they've been applied (e.g. output type verification).
