Modify hit test masks for tabs and tab close buttons
In preparation for landing rect-based event targeting
(issue 129794), the tab close button will need a hit
test mask and the hit test mask for a tab will need
to be modified. This will take into consideration the
possibility where the tab close button of one tab is
occluded by another tab when in stacked tab / touch
layout mode.
