[PTZ] Expose image capture pan & tilt only if PTZ permission is granted
This CL makes sure the pan/tilt capabilities/constraints/settings
are available only if PTZ permission is granted to the website when the
the MediaCapturePanTilt feature is enabled.
If the MediaCapturePanTilt feature is disabled, the pan/tilt (not zoom)
capabilities/constraints/settings are not available due to the presence
of [RuntimeEnabled=MediaCapturePanTilt] attributes in WebIDLs while the
zoom capabilities/constraints/settings is still available regardless of
the PTZ permission.
An upcoming CL regarding PTZ support in getUserMedia will address a
potential race condition that may happen if PTZ permission status is not
retrieved when getting pan/tilt capabilities/constraints/settings.
Manual test: https://ptz.glitch.me/
Explainer: https://github.com/w3c/mediacapture-image/blob/master/ptz-explainer.md
