Use correct language when propagating textures

[SinZ163]

This attempts to fix a situation where a mod (like FIASA) had a tilesheet reference explicitly loading a localized tilesheet when the user isn't playing in that language which can chain react into causing every content manager to load that localized version when its trying to propagate to each of their caches.

Thanks for the PR!

I think we can extend your fix further. The propagation is meant to replace the texture that would have been retrieved by a fresh Load. The contentManager.Load<T>(assetName) method calls LoadLocalized<T>(assetName, currentLanguage) regardless of the asset name's locale, which is handled separately. So we can probably strip out the custom language handling entirely here.

I rewrote the previous code to make it easier to follow, rebased the PR, and stripped out the language handling entirely. Could you run a test with Profiler for the case you mentioned to make sure it's still fixed?
