Patch - Adds component shutdown functionality - V13.6.1

Implements a shutdown mechanism for components and entities,
ensuring proper resource release and preventing memory leaks.

This change introduces a virtual `Shutdown` method to the
`Component` class, allowing derived components to release
specific resources when they are removed from an entity or
when the entity is destroyed. The `Entity` class now calls
the `Shutdown` method on all its components during its own
release process. The `EntityManager` now calls the
`release()` method when destroying an entity.

This enhancement ensures that resources, such as FMOD sound
objects and channels in the `AudioComponent`, are properly
released, preventing potential resource leaks and improving
the stability of the engine.
