HID: lenovo: Add support for Thinkpad X1 Tablet Gen 3 keyboard

The Thinkpad X1 Tablet Gen 3 keyboard has the same Lenovo specific quirks
as the original  Thinkpad X1 Tablet keyboard.

Add the PID for the "Thinkpad X1 Tablet Gen 3 keyboard" to the hid-lenovo
driver to fix the FnLock, Mute and media buttons not working.
