Bindings will only be executed once at initialization. The bug happend when more than once source can activate the same binding.
Binding can now be OneWay if at least one argument is a FieldNotify. Otherwise it needs to be a OneTime.
Binding that has hardcoded value, no paths, are now supported.

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.

- Add a border on each MVVM binding row in the list view of bindings that changes color to red/yellow if there is any error/warning for that binding
- detect if a property is bound to both a MVVM binding and a legacy binding at the same time and add a warning for it.

Add an option to show the detail view in the binding panel. This prevent the bad memory access in the customizer used by a the binding panel.
