Add support for on-device haptics

Home Assistant Android version: 2.5.0-full Android version: 11 Phone model: Google Pixel 4a Home Assistant version: 0.115.3

Description of ~problem~ feature request:

~My phone supports haptics natively, but I get vibrations when tapping on buttons in the front-end.~

Google Pixel devices have haptics, similar to iPhone devices, and is measured in ms. Instead of a single form of vibration, haptics provide subtle but differential feedback during interactions with the frontend such as tapping buttons or opening menus.

Per Apple’s Human Interface Guidelines, the following options are available for haptics and is currently implemented by devs, so they’re maximum compatible.

Thanks for looking into this @dshokouhi.

So we need to basically define what we expect them to do, does apple have the specific patterns documented? We probably need to do our own thing here if we don’t see anything defined.

Basically yeah.

A couple of things that could be useful:

1. https://developer.apple.com/search/?q=haptic
2. https://developer.apple.com/documentation/corehaptics/chhapticevent/parameterid/3114595-hapticintensity
3. https://developer.apple.com/documentation/corehaptics/chhapticevent/parameterid/3114596-hapticsharpness

I tried taking a look at this. Android does not really support the constants defined by Apple. Only a handful exist and thats only available to users on the latest version API 30.

I don’t see apple defining how many ms each of the above is mentioned. I think this feature was designed specifically for iOS so we may need to map our ms response for users who cant use teh constants up above. Additionally it will not be as easy to map them to iOS and as of now the external bus sends back everything we see in the link so we can’t really change that.
