jeff fisher a3748e48bc OpenXR related features and fixes.
-Adds support for getting velocity and accelleration through GetControllerTransformForTime.
-Adds mechanism for using openxr chain structs which are defined in and consumed by an extension plugin.
-Support for defining a swapchain and renderbridge in an extension plugin.
-Some OpenXR fixes related to runtimes not supplying tracking data of various types.  Basically if the data isn't being provided we should not copy it out because it might be full of nonsense.  Also we would generally rather preserve our last cached position than overwrite with zero/identity.
-Moving OpenXRPlatformRHI.h OpenXRHMD_RenderBridge.h and _Swapchain.h back to private folder.
-Previously one could not run the same haptic effect on two devices simultaneously and have it behave correctly because most of the per-effect-play data for each effect was shared by all controllers.  This refactors so that the necessary runtime data is per controller and the constant bulk data is shared by all controllers.
-Adding infrastructure for playing haptics on a VR HMD.
-Refactored haptic data resampling into the oculus plugin because that is plugin specific.
