Reworks LogicBlocks to ensure OnEnter/OnExit is called in the correct order for states that are reused.
[x] Adds support for multiple initial state types to the diagram generator
[x] Adds support for partial states spread across files to the diagram generator.
[x] Simplifies the LogicBlock core state change mechanism.
[x] Adds internal state to StateLogic so callbacks can be preserved inside the state rather than inside the logic block. This is the mechanism which enables the fix above.
[x] Updates all API usage, fixes tests, and introduces new tests for desired use cases.
