Shark and RUSS 3 torpedoes: make them behave like in E2140

[michaeldgg2]

Torpedoes, fired by Shark and RUSS 3, should behave like this:

• can be blocked by non-water terrain
• can be blocked by other actors
• can run out of fuel
• and mainly: when targeting water tile, they don't explode at that tile, they continue traveling until they either hit something (actor/non-water tile) or run out of fuel

Originally, this was supposed to be implemented as custom Torpedo projectile based on slightly improved Missile (OpenRA/OpenRA#21281). After discussion with the OpenRA dev team, it was decided that this behavior should be implemented directly in OpenRA.

Use #540 as basis.
