hwdb: add scancodes for AYANEO devices (#33378)

AYANEO has multiple models that all use the same AT Translated Set
2 Keyboard device with 3-4 buttons available. Starting with the
AYANEO 2 there was a change to the IMU programming they were using
that caused the scancodes to no longer present the correct values
in Linux. This change adds a blanket scancode mapping to present
the correct keycodes as designed by the OEM.

In some cases a kernel bug will cause the AT Translated Set 2
Keyboard to present as an AT Raw Set 2 keyboard. I have also
adjusted the scancodes for this scenario as well so they are
in line with expected behavior. Currently only the Kun is still
experiencing this bug.
