Enable Camera System to work with XR SDK / 2020.1 and above

XRTK - Mixed Reality Toolkit Pull Request

Overview

This PR enables the camera system to correctly work with the XR SDK plugin management and sets the camera at the correct height depending on the tracking space configuration.

Changes

• There is a new setting for camera data providers available in their profile: Tracking Origin Mode. If set to Device the scene origin is at the device height. That means Y = 0 is where the device is. If set to "Floor", the scene origin is at floor level, that means Y = 0 is where the floor is.
• Implemented support for the XR SDK Plugin System and removed obsolete API usage
• Maintained backwards compatibility to legacy VR using scripting define symbols. Let's remove that backwards support asap once @StephenHodgson upgraded all his projects

Wth man. I am starting to believe the pipeline does not pick up the scripting define symbols correctly.

Oh yeah. Actually my last commit broke something.
