* SpherePointer query optimization

The SpherePointer performs multiple queries per frame at times and with every collider returned it performs a costly GetComponent call on the collider to retrieve the NearInteractionGrabbable component.

This PR optimizes that logic by adding a LRU cache to the SpherePointer to cache the retrieved NearInteractionGrabbable component. The cache holds a user defined number of entries, and the cache is purged when the SpherePointer is destroyed.

Editor mode unit tests are implemented for the new utilities class LRUCache.

Previously, if the shader's maximum proximity light limit was reached, a warning would be logged and the lights discarded. I've changed this to keep all lights around on the CPU side and only send the first two valid ones to the shader. This helps with race conditions where multiple lights are added and removed in a single frame and eliminates a warning that was spamming to the log and degrading performance.

* Fix PokePointer hitting arbitrary colliders when touching volumes

For packed scenes the huge ray range used for Touchable volumes, regularly hits arbitrary colliders in the scene, instead of the actual touched object. Touchable volumes will now properly calculate the penetration distance into the object. Further PokePointer ray has been adjusted to only cast through the very touchable volume.

* Improve touch events for nested touchable volumes

* Add unit tests for the touchable volume raycasting and nesting
