DisplaySettings: Add hardware-framework support for tap-to-wake

Since we have tap-to-sleep globally, might as well support the
wake gesture as a standalone thing through the HAF. Place it in
"Display".

Bluetooth: disable scan icon when BT state is off

Usually onScanningStateChanged function should take care
of disabling the scan icon when the scan is completed.

But When the BT scan is going on and try to switch of the
BT, as onScanningStateChanged function doesn't have the
reference for scan icon it will not disable it, so disabling
is taken care in BluetoothSettings on receiving BT Off state.

On receiving BT Off state, disable the scan progress icon only
when available device category is present.
