MacViews: return screen coordinates for windowless events in |EventLocationFromNative|

Previously, we were returning 0,0 in this case. Returning screen coordinates matches
AppKit and is roughly congruent with what Windows does in this case.

Mac: Disallow dragging tab into blocked tabstrip

This is a really longwinded way for me to fix some NOTIMPLEMENTED spam,
though I'm pretty sure the thing that happens right now when you open
a certificate prompt and drag a tab into the parent window is bad.

This introduces a new method because we're not sure if it matches the
Aura semantics, and this is better than the nothing we were doing previously.
