Make the interop-layer work with components with custom name (#41207)

Summary:
This should fix
#37905 (comment)

When working on react-native-fast-image, we realized that the interop layer does not work for components where the exported name is different from the iOS class.

To fix this, we can use the Bridge to retrieve the actual view manager, given the component name.

This solution should be much more robust than making assumptions on the ViewManager name, given the ComponentName.

On top of that, we realized tha the interop layer was not calling `didSetProps` after setting the props, so we are invoking that.

[iOS][Fixed] - Add support for Components with custom names in the interop layer.

Pull Request resolved: #41207

Test Plan: Tested locally on an app created in 0.72 and 0.73 in Bridge and Bridgeless mode.
