Smoke-tests: simplify test map, speed up AI tests (#11393)

This update is primarily to help tests execut faster.
To do this, we simplify the map used for AI testing.

Notably, we have removed sea zones from the test
map, technology, and we have titled the starting
scenario in Russia's favor such that it can win
pretty quickly.

== Performance Impact ==

Full compile & test of 'smoke-testing' goes from
54s -> 18s

The AI game test on its own can now complete in
under 2s (previously was over 10s)
