[MVUX] [Bindable] attribute is not considered by uno's type info generator

[dr1rrb]

Current behavior

When we generate a _ViewModelwe are [adding a[BindableAttribute]`](https://github.com/unoplatform/uno.extensions/blob/main/src/Uno.Extensions.Reactive.Generator/Bindables/ViewModelGenTool_3.cs#L101). This attribute should be considered by the bindable type provider generator to generate the type info for bindings.

However it seems it's not : #2515 (comment)

Expected behavior

_ View models_ generated by MVUX should be binding friendly!

How to reproduce it (as minimally and precisely as possible)

cf. #2515 (comment)

Note: AN hypothesis would also be that MVUX's generator is executed after uno's type info generator.
