Improvements

• Asset Pipeline: Fix race condition that may occur when downloading non primary artifacts from cache server

• Profiler: Load icon changed to more clearly read as "Load".

• XR: XR Statistics caches thread-safe stats that only get promoted to 'live' data after a render pass. However a number of data points need to be 'initialized' before we actually render a frame (like Frame Rate).

System Requirements
