Add Find Artifact victory condition in Editor

[Districh-ru]

relates to https://github.com/ihhub/fheroes2/issues/8717

This PR implements "Find Artifact" Victory condition. The Magic Book and the Spell Scroll artifacts cannot be selected for this case. It also:

• makes the drop lists to follow the UI style (Good/Evil);
• makes the UI not to reset the values when the condition is changed: when you return back to the previous condition the last value will be restored until the dialog is closed;
• slightly speeds-up rendering сру changes in special victory conditions;
• makes the drop list items be horizontally aligned with the upper (selected) condition icon and text. The icon for the Ultimate Artifact is temporary and should be updated to a more proper one later.

I've added @zenseii to have an opinion about newly added artifact name and description.
