[mediacapture-image] Pan and Tilt Constraints

dsanders11 has just created a new issue for https://github.com/w3c/mediacapture-image:

== Pan and Tilt Constraints ==
What are the feelings on adding a pan constraint and a tilt constraint?

Both settings are part of the UVC spec. They're supported on Windows ([getRange_Pan](https://msdn.microsoft.com/en-us/library/windows/desktop/dd376305(v=vs.85).aspx) and [getRange_Tilt](https://msdn.microsoft.com/en-us/library/windows/desktop/dd376309(v=vs.85).aspx)) and via V4L2 on Linux (`V4L2_CID_PAN_ABSOLUTE` and `V4L2_CID_TILT_ABSOLUTE`).

They do not, however, appear to be supported on Android via either API (`android.hardware.camera` or `android.hardware.camera2`). Most built-in cameras on Android devices likely don't support them anyway, from my experience.

Logitech webcams support pan and tilt and it would be a great resource to have in the spec for fully controlling these types of cameras.
