[Feature] Simpler setup: Resolving viewmodels for views

[BurkusCat]

Is your feature request related to a problem? Please describe.
The ResolveBindingContext markup extension is a bit verbose and requires you to repeat the x:DataType= that you may already have. Is there any way this can be made simpler?

Describe the solution you'd like
A one line solution that sets the datatype and resolves the viewmodel would be brilliant. Not all users use x:DataTypes in their apps currently so they would see added benefits of improved binding performance + compile time errors for binding failures.
