Extract strings from resource renderer

[Mailaender]

Completes #10475

[RoosterDragon]

Change looks good to me.

This is failing because #21389 now complains it doesn't know how to lint it due to the LoadUsing. I'd be fine hacking in a custom check just like we have for GameSpeeds.

OpenRA/OpenRA.Mods.Common/Lint/CheckTranslationReference.cs

Lines 131 to 137 in 10d7436

	// HACK: Need to hardcode the custom loader for GameSpeeds.
	var gameSpeeds = modData.Manifest.Get<GameSpeeds>();
	var gameSpeedNameField = typeof(GameSpeed).GetField(nameof(GameSpeed.Name));
	var gameSpeedTranslationReference = Utility.GetCustomAttributes<TranslationReferenceAttribute>(gameSpeedNameField, true)[0];
	testedFields.Add(gameSpeedNameField);
	foreach (var speed in gameSpeeds.Speeds.Values)
	usedKeys.Add(speed.Name, gameSpeedTranslationReference, $"`{nameof(GameSpeed)}.{nameof(GameSpeed.Name)}`");
