Introduce eCanOccludePresentation layer flag

Sets a property on a layer hierarchy indicating that its visible region
should be considered when computing TrustedPresentation
Thresholds. This property is set on a layer and inherited by all its
children. The property is then passed via windowinfos so the
TrustedPresentation controller can determine which windows to
use when computing the thresholds.
