The VR BottomBar now works behind geometry / parts and renders on top of them.

Stylize Toolbox Asset Preview layout

Added Client Guid, User Guid and Session Guid tracking info to Backtrace and Startup teleemetry. Deprecated ClientID field from backtrace.

Implementation of LifecycleManager and lifecycle management of components.

Replaced all Analytics::Event::getSessionId and clientId with Studio's Launchtracking info ones.
