20-mouse.conf: add CPI for Steel Series Aerox 3

We need to hardcode the CPI value of the Steel Series Aerox 3 mouse as
it is not possible to read its CPI from its descriptor. There are three
variations of the mouse: wired, wireless bluetooth, and wireless dongle.

BUG=b:226707569
TEST=Do not currently have the mouse, but was able to build & flash to device without obvious errors.
