Adjusting bounds of system_icons and statusIcons so they align with cursor hover state

Changing bounds of them both to be wrapped_content instead of match_parent - then when we introduce hover state for system_icons, it can simply align with view bounds instead of doing custom measurements.
StatusIconContainer required changes in onMeasure, otherwise it was always taking all available space vertically.
Both views are still centered vertically, no changes in that regard..

Test: Checking how status bar looks in different orientations on launcher/keyguard
