refactor: remove block builder in favor of checkpoint builder (#19688)

- Remove legacy buildBlock() method from FullNodeCheckpointsBuilder
- Migrate EpochPruneWatcher to use checkpoint-based APIs
(startCheckpoint() + buildBlock())
- Add ICheckpointsBuilder and ICheckpointBlockBuilder interfaces to
stdlib to avoid circular dependency between slasher and validator-client
- Delete unused IFullNodeBlockBuilder interface and BuildBlockResult
