Add mechanism for a task's windows to be trusted overlays (SF)
- Add a layer state to indicate that this layer and its children
in the hierarchy are trusted. This can only be set by callers
holding ACCESS_SURFACE_FLINGER, and will be used for the PIP
task layer to indicate that activities in PIP are trusted (as
they are controlled only by the user and SystemUI)
