[decompiler] Clean up config more

[water111]

This removes the global config finally! It also splits up the main config into an inputs/hacks file to keep the main config a little bit shorter.

Also the big offline test script was revived which will now test:

• cloning
• building everything
• unit tests
• offline decompiler tests
• full decompilation (just checks it doesn't crash)
• asset building
• asset checking (compare against game)
• game building
• boot game
