Add Trevi InnovAqua variable speed pool heat pump (#5764)

Adds a device config for the Trevi InnovAqua variable speed pool heat
pump (Tuya product id `bqfay9re2z3hfhoq`, local protocol 3.5).

All datapoints were confirmed from a full local dump of my own unit:
on/off (dp1), Celsius setpoint (dp2) and inlet water temperature (dp3),
mode silent/powerful/heat/cool (dp4), fault bitfield (dp9), display unit
(dp17), and the native Fahrenheit setpoint (dp25) and inlet water
temperature (dp26).

The climate uses the Celsius datapoints. The device's native Fahrenheit
setpoint and water temperature are exposed as separate `number` and
`sensor` entities. I also tried modelling the climate directly on the
Fahrenheit datapoints (dp25/dp26), but tuya-local does not create the
climate entity for it on this device, so Celsius is used for the
climate.

Validated against `device_config_schema.json` and `yamllint`.
