[Enhancement] Add Bindings support for ImageResourceExtension

[Cfun1]

Summary

With the actual ImageResource xaml extension ImageResourceExtension.shared.cs it is not possible to use Bindings.

What do you guys think about implementing a converter for this extension like it is already done for some of the converters?

I have tried to derive from BindableObject to use bindable properties but the main issue is that ProvideValue() will always fire first before the property changed event does, so it seems using Bindings with IMarkupExtension won't be straightforward.

As a solution:
- Create a new converter for the same purpose.
- Or apply/update/resolve/manage the Bindings our-self inside ProvideValue() starting from a string property (Path & Source of Bindings) set by the dev (seems there is some approaches to it but they look complicated not practical IMHO https://stackoverflow.com/a/43866357/).

Who Will Do The Work?

• I am willing to take this on myself
• Just putting this out there for someone to pick up
