Minor adjustments for D2k AI

[Porenutak]

• Turns on AutoContrete for AI players even when autocontrete is disabled. See discord discussion here: https://discord.com/channels/153649279762694144/388282819371204608/1173992200837812234
• Delay upgrades and tech building until mid game. (AI will not be eco broke right after first rush)
• Increase Production building limit up to max production speed.

if AI doesn't expand then won't maxing our production speed just bankrupt it?

[Porenutak]

AI build more buildings only when have more that 5000$. Thats a happen in very late game where AI also have some carryalls. To be fair AI eco is broken most of the time. To address this problem complete overhaul will be needed.
I adress this problem here:
#20577

[Porenutak]

I did more testing. AI will never go broke because of maximizing production. Carryalls boost eco enough. Problem is there is not enough space for all buildings on some maps. (without expansion)
Changed building limits for big production buildings from 3 to 2.
