Add xr::DispatchTable for XrUtility (#104)
* Add xr::DispatchTable for XrUtility Add xr::DispatchTable for XrUtility to support libraries that lazily loads openxr_loader without static link to xrFunctions. Also simplify how to call extension functions through global dispatch table. * Add all XrUtility headers to solutions
