Move ViewCapture On/Off controls to QuickSettings Tile.

Rather than use a feature flag for this feature, the on/off state will
be stored as a system setting and will be changed via a QuickSettings
tile.

Bug: b/264452057
Test: Verified that the new QuickSettings tile doesn't crash via normal
interactions (pressing, long-pressing, etc.). Also verified that
ViewCapture is turned on when the QuickSettings tile is in the enabled
state and is turned off when it is in the disabled state.
