PreventCollision with strap component while buckled to it (#2694)

* AvoidCollision if collided entity is the one that the character is buckled to

* Attempt to PreventCollision after the player is unbuckled but still colliding with StrapComponent

* Moved PreventCollide to the Shared script.

* Add WakeBody to keep updating the physics collision while being on a collidable strap component.

* Addressed some of metalgearsloth's suggestions:
- Made EntityBuckledTo,IsOnStrapEntityThisFrame and DontCollide not virtual
-Made EntityBuckledTo nullable
-Don't call update on Paused BuckleComponents
-Removed EntityBuckledTo variable declaration in BuckleComponent because it's not needed anymore
-Call TryUnbuckle if (!IsOnStrapEntityThisFrame && DontCollide) to set BuckledTo entity to null.

* Renamed variable EntityBuckledTo to LastEntityBuckledTo

* As per DrSmugLeaf suggestion: Added [ComponentDependency] to the Body variable.
