At initalization, one at the time, the source initialize and then execute the bindings. Binding can use a source a soon to be initialize source and a binding can set the value of a source. Both cases need to be taken into account when sorting the sources.
When initializing, the binding can trigger a FieldNotify of another initialized source that can trigger that same source that try to initialize. Add a message if that occurs.

Early runs of async loading in the editor were tripping the TStrongObjectPtr's check that it can only be created on the game thread. The was caused by the FMVVMViewBlueprintCompiler::BlueprintView field. Since we're dealing with a non-UObject here, we typically introduce the object reference either by reflecting the struct, or forcing it to inherit from FGCObject.
However, we can also take advantage of the ownership structure. Both the FMVVMViewBlueprintCompiler and UMVVMBlueprintView are owned by UMVVMWidgetBlueprintExtension_View. Technically, FMVVMViewBlueprintCompiler doesn't need a reference to UMVVMBlueprintView if it's already owned by the extension.

Upgrade the overrides and callsites in all of Epic's code.
Every class that can be subclassed by licensees that has its override change needs to keep the old version of the function as deprecated. Otherwise subclasses that call Super::GetAssetRegistryTags will have a compile error instead of a deprecation warning.
Several classes had their own extension method for GetAssetRegistryTags being passed on to user data classes. Updated all of those to take FAssetRegistryTagsContext just like GetAssetRegistryTags does.

Add a different "key" structures to prevent mistakes with indexes.
Unregister the delay bindings when the source is released.
Store the FieldId, in the source itself. That reduces the amount of work when loading the view.
Add option to delay the events initialization (like we do for bindings).
The binding to evaluate "long path" view models are now separated from regular bindings.
