HID: uclogic: Add support for XP-PEN Deco LW

The XP-PEN Deco LW is a UGEE v2 device with a frame with 8 buttons.
Its pen has 2 buttons, supports tilt and pressure.

It can be connected by USB cable or using a USB Bluetooth dongle to use
it in wireless mode. When it is connected using the dongle, the device
battery is used to power it.

Its vendor, product and version are identical to the Deco L. The only
difference reported by their firmware is the product name.
Add a quirk to support battery reporting on the wireless version.
