Replaced video calling/camera permission dialog with a toast.

Since we are given the camera permission by default for video calling, we don't
need to request it from the framework. But, for privacy reasons, we still need
to tell the user that we have it.

Since we're changing the preference for call composer, v10.1 users will see this
this toast again if they've never made a video call.

The toast is shown in the following situations:
1. If a user receives a video call
2. If a user makes a video call
3. If the user opens call composer

The toast doesn't show:
1. If the user has already seen the toast anywhere before
2. If the user has revoked the system permission and grants it
with a system dialog
