* Use Virtual Screen Coordinates in more places

- When setting widget bounds. - Workspace Manager - When resizing - Restore bounds * Refactored ScreenPositionClient to manage Screen coordinates for different configurations. * Renamed GetBounds/SetBounds methods to GetScreen/ParentBounds to make it clear that in which coordinates you're dealing with. * I used InScreen/InParent for RestoreBounds because RestoreParent/ScreenBounds sounds strange. Converted Linux/Aura to use ScreenPositionClient. BUG=123160 TEST=several tests are updated to match VSC. added screen_ash_unittests. I'll update rest of tests when this is enable by default.
