[FR] Multiple Attributes support

[oerix]

Can we have an option to select more than one attribute for Button entities please?

Example: For Media player card, I can choose to have the 'Series name', alongside the 'Channel' name.

The current options last changed, entity state should all be moved inside the attribute dropdown as well, just like HA Tile card shown below. It is much cleaner and easier UI with support for multiple attributes.

Hi! This feature will finally be the default in all cards and sub-buttons in v3.4.0! 🍻
