Massive nation improvement 🤖 (#3761)

## Description:

- Hard / Impossible nations in team games auto-stop trading with all
enemies
- If there are a LOT of nations on the map (Enzo stream with 400 nation
HvN private games) they no longer start with a city, they start with eco
(port / factory) because they cannot gain much gold from bot-killing
- Impossible nations built way too many missile silos sometimes, caused
by the SAM overwhelming logic. Fixed now.
- In public HvN games with 5M starting gold, nations placed their
structures way too fast, which slowed down their expansion. And humans
could easily cause a lot of damage with one atom bomb. Now their first
structure is a SAM (on hard / impossible) and they wait between their
earlygame structure placements.
- Nations now spread out their port placements more evenly
- Nations are now able to attack much stronger enemies in team games
(They can expect donations)
- Improve performance a bit by adding more early-returns (Dont run any
nuking logic if nukes are disabled, no alliance logic if alliances are
disabled, no boating logic if transport boats are disabled, ...)
- Fix some of the "cannot send troops" messages in the console
(DonateTroopExecution)
- Nations build their first missile silo sooner, they should also build
more SAMs
- Nations spend their gold better after reaching the save-up-target
(previously they stopped nuking)
- Optimized save-up-targets for team games
- The richest impossible nation is nuking very dense players now (lot of
structure levels on a small island)

### How does a 5M gold HvN start look like now?
