Small improvements to the tuya ts0021 quirk

[rbaron]

Proposed change

Some cosmetic changes to the tuya.ts0021.TS0021 quirk:

• Hide the "Opening"/"Smoke" sensor. The IaSZone cluster causes this device to be recognized sometimes as an Opening sensor, and sometimes as a Smoke sensor (see [Device Support Request] TS0021 _TZ3210_3ulg9kpo Tuya 2 gang switch #2847). This is confusing, so I removed that cluster.
• The logbook only shows a generic "Attribute Updated event was fired" for every action (single, double, long presses). This is also confusing ([Device Support Request] TS0021 _TZ3210_3ulg9kpo Tuya 2 gang switch #2847 (comment)). I added a new zha_event that logs more specific actions like "Button 2 Double Press". I kept the old events, as not to break existing automations.
• The battery always showed up as unavailable. I tried a bunch of things, including reading the power clusters attributes directly for the percentage_remaining, using the TuyaPowerConfigurationCluster2AAA, the TuyaNoBindPowerConfigurationCluster, waiting for 24h. But nothing seemed to work. It's likely that I'm missing something, but it's possible that the device does not expose its battery voltage/percentage. Since it's not working, I also removed the power clusters, so they don't show on the UI anymore.
