HID: steelseries: Split Arctis headset driver into separate module

Browse Source 
Move all Arctis headset code (battery monitoring, wireless status,
power supply registration, raw event handling) from hid-steelseries.c
into the new hid-steelseries-arctis.c driver module.

hid-steelseries.c keeps the SRWS1 racing wheel and the MSI RGB LED
devices, while hid-steelseries-arctis.c handles the Arctis 1 (Xbox) and
Arctis 9 wireless headsets with their own device table, probe, remove,
and raw_event implementations.
