AnyCollider context

[oxkitsune]

Objective

Provide a way for the methods in AnyCollider to obtain extra context from the ecs/entity it is attached to.

Solution

• Add a Context GAT to the AnyCollider trait
• Optionally query for this context in the broad/narrow phase
• Pass the Option<Context> to the AnyCollider methods when called

---

Changelog

• Changed: AnyCollider requires a Context GAT, to provide additional context from the ecs.

This is a draft, as I'm looking for comments/feedback on the implementation.
Perhaps there is a better approach, but I'm not super familiar with avian's internals. Or this not something avian is looking for. either way, I'm curious to hear what you think 😄
