Proposed change

Use context instead of stateObj for card features. It was already used in the editor and will open the possibility to have card features for other type of card (e.g. area card by passing an area_id)

All the HA card features has been migrated in this PR.

Custom card features needs to migrate to this new API :

• supported: (stateObj) => boolean is replaced by isSupported: (hass, context) = boolean
• context property is set to card features instead of stateObj

However, a backward compatibility has been added to avoid breaking change. A blog post will be written and the dev documentation will be updated.
