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.
