refactor!: stateless useFiber, ContextBridge

[CodyJasonBennett]

Refactors useFiber and useContextBridge to not depend on our favorite export. traverseFiber is renamed to traverse with ascending moved beyond the selector, and removes FiberProvider and the unused useNearestChild, useNearestParent, and useContextMap hooks.

@CodyJasonBennett what's the plan with this? I'm going to spend some time investigating its fine this afternoon. Curious to know if this will come in soon.

Not needing the fiber provider looks like a great change. I'm going to copy this and have a play.

Edit: It doesn't look like it works 100% of the time. Mostly needing to re-render/HMR to find expected meshes. Is it not concurrent mode safe I guess? Let me test without suspending.

Edit (2): Yes that seems to be the problem.

Will backport as a minor release.
