Do not create a number LED brightness entity for Xiaomi Miio devices that do not support it

[bieniu]

Breaking change

Proposed change

After #60134 number LED Brightness entity is created for models that don't support it. FEATURE_SET_LED_BRIGHTNESS uses the select platform for most of the models. With this change, mistaken created entities will be removed and number LED Brightness entity will be created only for ZA5 fan.
