Allow secondary_info with custom attribute when state is off

Currently it is not possible to show secondary_info with custom (non-default) attribute when state is off.

Allow a secondary_info (like brightness or brightness_pct) when entity’s state is off. Perhaps divide them into

• secondary_info_on and
• secondary_info_off

Target: use secondary_info_on: brightness_pct when on and secondary_info_off: last-updated when off.

State on is fine:

State off is missing secondary_info:

Used for example:

  - type: custom:slider-entity-row
    entity: light.lampe_tisch
    name: Lampe Tisch
    hide_when_off: true
    full_row: false
    min: 1
    max: 100
    step: 1
    attribute: brightness_pct
    toggle: true
    show_state: true
    state_color: true
    secondary_info: brightness
    state_header: ''
    column: false

Anything to the left of the slider is handled by Home Assistant and will only have the features that any other row has.

Yes. In exactly the same way as slider-entity-row does. No more. No less.
