[XR] GearVR HMD and Remote Controls are missing or incorrect

[jackpr-unity]

HMD

• HMD does not have controls for the "back" "start" or Dpad buttons shown in the Oculus documentation (https://developer.oculus.com/documentation/unity/latest/concepts/unity-ovrinput/)

Remote

• "Back" button does not function for Remote
• Touchpad is exposed as a Vector2 control in the InputAction bindings list, but is documented as button input on the Oculus website (https://developer.oculus.com/documentation/unity/latest/concepts/unity-ovrinput/)
• The Remote has a combinedTrigger. Is this valid? The combined Trigger does not work properly for left hand. It should produce a negative value when the controller is set to left hand, but the value is observed to remain positive.

As of 2018.3.0b2 with package version 0.0.7-preview lots has been fixed. Current state is all good except:

HMD does not have controls for the "back" "start" or Dpad buttons shown in the Oculus documentation (https://developer.oculus.com/documentation/unity/latest/concepts/unity-ovrinput/)

[jackpr-unity]

As of 0.0.14-preview there is an inconsistency between the touchpad axis2d and pressed/touched namings.

the axis2d control is called "joystick"
the pressed/touched namings correctly use "touchpad" in their names
