Introduce World Debug

[Deewarz]

Main

• Introduce World Debug UI
  • Vehicle spawner
  • Season manager
  • WeatherSet manager
  • Time manager
  • Traffic stuffs

Also

• Move vehicle spawn from DevFeatures to WorldDebug
• Remove district debug that doesn't work (to be put in WordDebug in the future)
• Cleanup DevFeatures (alphabetical order)
• Remap DevFeatures shortcuts :
  • F1 => WorldDebug
  • F2 => PlayerDebug
  • F3 => VehicleDebug
  • F4 => (non working) Camera Studio
  • F5 / F6 => Human debug (to be moved to WordDebug in the future)
  • F7 => CrashObject debug (to be moved to WordDebug in the future)
• Remove unecessary <external/imgui/wrapper.h> import in debug UIs
• Add C_GameGfxEnvEffModule::GetCurrentWeatherSetName

Known issues

• Season can't be changed because of the hook (requires Disable Season and TimeFlow on game ready #85 to fix)
• As for all UIs, the console must be open to see the cursor.

Next steps

• Rethink debug UIs #87
