[AssetPipeline] Dependency Tracking about prowl HOT 3 CLOSED

Serialization now records the assets it comes across, so assets now track things they depend on.
So a model will record all the textures/materials it uses in "$dependencies" in the resulting SerializedProperty.

Next up is a way to get that information
Maybe
AssetDatabase.GetDependencies(FileInfo)
Maybe MetaFiles should also record that dependencies list for faster loading? that way it doesn't have to load the asset to get the dependencies.

Ok i have Dependencies being stored in Meta files now
Theres an issue though

Scenes for example serialize GameObjects into a SerializedProperty before being serialized AGAIN into the SerializedAsset
Im not sure how to get the dependencies from the Gameobjects to the final SerializedAsset
Since at the moment their returned in the context after serialization not the SerializedProperty, and even if they were inside the SerializedProperty as a field they would only exist for Compound properties, which fails for Scene's since the GameObjects are stored in a List property. I could work around with on the Scene side of things, but i'd rather the Dependency tracking be able to handle any case including this one.

So need to figure out a way for dependencies to support serializing already serialized things with their own dependencies.

Ok added SerializedProperty.GetAllAssetRefs(ref Hashset)
Which returns all AssetRef.AssetId's found inside the SerializedProperty

Im not a fan of hardcoding AssetRef stuff into SerializedProperties but it's the only cleanish solution I could come up with, that didn't involve any significant rewrites.

Now all asset types should fully track their dependencies inside the Meta File, and everything when serialized outputs the assets required to deserialize the resulting SerializedProperty! :D
