[Feature Request] Make resource loader generic

Currently I need to manually cast the type like this:

val scene: PackedScene = ResourceLoader.load("res:/xxx.tscn") as PackedScene?

Would be cool to have it like this:

val scene: PackedScene = ResourceLoader.load("res:/xxx.tscn")

// or

val scene = ResourceLoader.load<PackedScene>("res:/xxx.tscn")

Currently C# has it in a generic way

I find this a good idea. It would be consistent then.

We can do a similar operation like with getNodeAs. We can add As suffix as an extension function.
