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.

MVVM: Big rework of the MVVM view compiler. It add supports for conversion function to go from complex to simple. Supports pin split on simple conversion function. Add ability to to support setter function with more than one argument. Build the list of all the sources.

[REVIEW] [at]editor-ui-systems
#tests Refactored some code so property is returning a derived class but binding is refering to data from base, abstract, class.

Update GetBindingInfoFromFieldPath to support viewmodel inside another viewmodel. Add unittest for the function.
Add DoesInitializeAtConstruction on the view class. That is to support manual initialization. When the flag is false, the user is responsible for initializing the view.
Add ReevaluateSourceCreator. A source that was discovered at compile time and added to the list of SourceCreator may need to be evaluated if the path contains notify. That function is similar to SetViewModel but finds the new value from the SourceCreator.
Fix issue when a binding destination can't be evaluated at initialization. Since we only reactivate the bindings link to a source in SetViewModel, some bindings were never registered and never executed after the SetViewModel properly set the binding destination.
Update the view class ToString functions with the new flags.
Prevent adding a new binding when the editor data contains a conversion function and a regular function. That may occur when the user started with a regular binding and changed it afterward for a conversion function. We may not want to reset the binding to be non destructive.
