Use rounded icons in QS

Updates for QS icon resources:
        - Airplane mode
        - Alarm
        - Bluetooth
        - Flashlight
        - Cast
        - Data saver
        - Do not disturb
        - Edit (pencil icon)
        - Nightlight
        - Invert colors
        - Location
        - Settings cog
        - Wifi
        - Hotspot

* also renamed resources to have canonical names (e.g.,
ic_qs_bluetooth.xml instead of ic_qs_bluetooth_enable/disable), because
we are drawing slashes at runtime.

Some resources need animations:
        - Rotation
        - expand/collapse caret
        - Hotspot transient

Test: visual
