Disable logic for dying entities

[Noah2610]

A bunch of logic should be removed once an entity enters LifecycleState::Death. A bunch of components should be removed, and EntityConfig events logic should stop.

[Noah2610]

For dying entities, delete components:

• Velocity
  Without velocity, all movement-related logic is stopped
• Gravity
• Collider, Collidable, Solid
  Without collision components, collision checking is stopped
• LedgeDetector Corner detectors will still run, but won't affect anything if
  their parent entity doesn't have LedgeDetector anymore
• EventsRegister
  Removes any custom logic
