Ported Survival01 to Lua

There are three difficulties available, you can switch between them ~~[here](https://github.com/OpenRA/OpenRA/pull/6934/files#diff-55fbe32fb7b1873068357932ff886578R1)~~ ingame.

Still some open points, should...
- ~~I add map.png from the allied missions?~~
- you be able to build medis and spys from [barracks](https://github.com/OpenRA/OpenRA/pull/6934/files#diff-2d8fd8a8f219058709870221e874fd33R1240) (without tent) as well?
- the soviets [repair](https://github.com/OpenRA/OpenRA/pull/6934/files#diff-55fbe32fb7b1873068357932ff886578R319) their buidlings?
