Add secondary info type option to Tile card

[MadMaxMcKinney]

Proposed change

This PR provides an optional setting to the Tile card where a user can hide the state value. This is useful for Entities like Buttons where the state is often not useful information, or for navigational elements.

This PR by default keeps the state information shown, so existing dashboards should remain unaffected.

To expand on this feature, and the reason the UX is a dropdown, is I think adding template support or manual overrides for the secondary information in the Tile could be a great next addition! These additional options can be slotted into the dropdown.

This should be translated/localized

I think the YAML parameter should be just secondary_info to match what we have in the non tile cards (where we have secondary_info and secondary_info_attribute).

Also in the non-tiles we have more secondary info options. Shouldn't those then also exist in the title cards?

[MadMaxMcKinney]

@spacegaier Good call, I'll add more of the expected secondary options and localize it using the strings from the existing tags.

Hi !
Thanks for the proposal. We discussed that with @bramkragten and we think it can be nice to go a little futher to allow flexibility

Here's the proposal

Allow array of options for secondary_info witch can using state, attributes, last-changed, last-updated.

secondary_info:
   - state
   - preset_mode
   - temperature

It will display : Heat · Eco · 22 °C

As it's a bigger feature, I will make a PR for that proposal.
