feat: make SVG textures usable as textures directly

[GerkinDev]

This PR makes USvgTexture inherit from texture, with all required methods proxied to the underlying Texture instance property.

I tested it with UI widgets, and it works well.

[GerkinDev]

OK I made it work :)

It is probably not the best way to do it, but feel free to modify it to your liking

This is super fun! I was actually thinking myself to do something like this, but felt the task is very daunting. I'll review & merge it upstream if all good.

May I ask your use case?

[GerkinDev]

For now I only use it for UI components, I still prefer to edit my graphical resources in a text editor ;)

here is a demo of what I achieved by cutting an svg into pieces with masks, importing them to UE and using material instances to rotate them
This way I checked out that the proxy works also for material transforms

I'll test your PR on android/ios/mac/win & then merge it. Important to also test Shipping & Packaged builds, since they behave differently & it took me a while to properly get a packaged build to work the first time round.

[GerkinDev]

Yeah OK perfect, I didn't used android/ios/mac/linux at all during dev, only windows. But if it works everywhere, I'm the happiest guy on earth :)

The most probable thing I see is that some methods might need to be proxied too; I did not proxy everything, just the minimum to work in my use case.

Oh and there is still a minor issue: it seems that the texture needs to be re-baked every time at runtime in standalone builds. It works, but cause a bit of lagging when the texture loads the 1st time. I don't understand a thing about mips & stuff, but I feel like some baked data is not serialized/deserialized correctly, and is thus recomputed at runtime.

[etodanik]

Yeah, we should fix that. I also had serialization issues at first, so I might be able to find the problem. But yea, before merging I want it to work cross platform & properly serialize/deserialize without runtime cost. I'm a bit busy for about 1 week, so if you get to it before then, it would be super nice. Otherwise, I'll take a look in about a week.
