AX: Fix mac zoom-for-dsf accessibility hit testing.

This patch addresses the wrong hittesting as a result of zoom-for-dsf.
1. The hit testing point is always converted to physical space
   since it is always given in DIPs (regardless of zoom for dsf).
2. GetViewBoundsInScreenSpace now returns "blink space" coordinates,
   meaning physical if zoom-for-dsf is on and DIPs otherwise.
3. The result of GetBounds is adjusted to DIPs if zoom-for-dsf is on,
   since it returns "blink space" coordinates.

I left a few TODOs which I plan to address after this issue is fixed.
I believe that we should have consistent non-blink spaces in this area
of the code, so it's easier to reason about (and so we can limit the
IsUseZoomForDSFEnabled checks to only a few locations)
