[mtl surface] Allow setting swap interval to 0. Note however that vsync needs to be turned off at the OS level for that to work smoothly. Otherwise, we get jittery frame rate with stalls when we run off of drawables (I suppose? should investigate some more). 

This can be done with Quart Debugger in Additional Tools for XCode.
