Bug Description

Evacuate command button should always be displayed in multi-selection whenever any unit is selected that can be evacuated to make it consistent with attack-move command button behavior (visible whenever any unit across the selection allows attack-move).

Right now, the evacuate command button is only displayed in multi-selection if all units have the same variant (see #2829) AND if the command button is in the same slot across all of them.

To make this command-button behavior consistent with the attack-move command button, it should always show up in multi-selection and evacuate all vehicles that have stuff inside of them.

Reproduction Steps

Compare multi-selection between busses / ambulances / helixes / chinooks / etc.
