Fix title vrdisp

[hamishwillee]

VRDisplay.hardwareUnitId and VRDisplay.resetPose both misnamed with incorrect prefix VRDevice.

This also fixes VRDisplay to mark all properties as deprecated (as per BCD and lower-level docs) and to merge the separate sections "deprecated methods" and "obsolete methods" back into the main methods/properties - since if all are deprecated these are not helpful categories.
