HID: steelseries: Add support for Arctis Nova 5X and Nova 7 families

The Arctis Nova 5X, Nova 7 Gen2, and Nova 7 2026 refresh headsets answer
status polls, but also send unsolicited battery and connection updates
on a second HID interface (interface 5). Use that interface through
async_interface so the driver does not have to poll. Add request and
parse helpers for the Nova status format (0xb0/0xb7/0xb9/0xbb opcodes).

The original (pre-Gen2) Arctis Nova 7 family answers the same status
opcodes on the same interfaces, but reports battery capacity as a
discrete 0-4 level instead of a raw percentage. Add a second parse
function that maps that level through steelseries_map_capacity(), and a
separate device_info so the two capacity encodings cannot get mixed up.

Add the fourteen USB product IDs that share these protocols:
