refactor: Remove PromoteSafeEvent

[pcw109550]

Description

Removes PromoteSafeEvent.

PromoteSafeEvent was emitted from IndexingMode and EngineController. EngineController was the only one consumed the PromoteSafeEvent.

IndexingMode was injected with EngineController at #17061 as using the ForceResetNotifier interface. Added the EngineController interface to support more engine controller procedural method call like PromoteSafe method.

Tests

All existing tests pass.
