Add setHasOverlappingRendering() method

View.hasOverlappingRendering() is an important performance tweak that
subclasses can override to do the right thing return false when appropriate
to avoid expensive operations when view is translucent).
But this requires subclassing View to get this behavior.

This new API allows the property to be set from outside, enabling
standard views to have this behavior set. When the new method is called,
the behavior will derive from whatever it was set to. Otherwise, it
will default to the old/overriden behavior.

Issue #16561361  Make hasOverlappingRendering settable from outside/XML
