fix(core): Add unbounded to the XRFeatureOptions to be used in world.create.

Summary: As is called out by the developer in https://fb.workplace.com/groups/1486811539191458/permalink/1541691123703499/ that unbounded is not supported as a part of XRFeatureOptions in world.init. Adding this feature to support unbounded in IWSDK.
