hwmon: (aquacomputer_d5next) Add support for Aquacomputer Aquastream XT

Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer Aquastream XT watercooling pump, which communicates
through a proprietary USB HID protocol. Implemented by Leonard Anderweit
[1] [2].

Coolant temp, fan IC and external temp sensor readings are available, along
with speed and voltage of both the pump and optionally connected fan.
It also exposes pump current.

Additionally, serial number and firmware version are exposed through
debugfs.
