Expose entity type Valve with HomeKit Bridge integration

## Expose entity type Valve with HomeKit Bridge integration

That would be great if we can expose entity type Valve with HomeKit Bridge integration.

**Additional context**

I'd like to control my sprinkler valve and make it accessible with the iOS Home application.

It can be exposed as 4 HomeKit types according to HomeKit doc: [HMCharacteristicValueValveType](https://developer.apple.com/documentation/homekit/hmcharacteristicvaluevalvetype
):
Type | Key
-- | --
0 | Water Valve |
1 | Irrigation (Sprinkler) |  
2 | Shower |  
3 | Tap / Faucet


Review the HomeKit Bridge integration and Apple’s HMCharacteristicValueValveType documentation linked in the issue. Determine how a Valve entity should map to the four HomeKit valve types, then verify that a sprinkler valve can be exposed and controlled from the iOS Home application.
