I observed [NSTrackingArea rect] becomes de-synchronized with the view
frame with some unknown condition, and fails to track mouse movement on
some area of the view. Specify NSTrackingInVisibleRect option to let
Cocoa automatically update NSTrackingArea, which also saves code for
synchronization.

Fixes: 91aa508d0274 ("ui/cocoa: Let the platform toggle fullscreen")
