Import name conflicts: Suggest adding "hide" on one of the conflicting imports

[rrousselGit]

Consider:

// a.dart
class Foo {}

// b.dart
class Foo {}

// c.dart
import 'a.dart';
import 'b.dart';

void main() {
  Foo(); // Conflict, defined in both `a.dart` and `b.dart`
}

Going through imports to manually add that hide Foo; on the relevant import is tedious.

Could we add a quick fix for it? When applied on Foo(), it could suggest:

• Add hide Foo to import 'a.dart'
• Add hide Foo to import 'b.dart'

Supporting static extensions conflicts too would be great.

Summary: The issue is that importing multiple libraries with the same class name (Foo) leads to a conflict. The user suggests adding a quick fix to automatically suggest adding hide Foo to one of the conflicting imports when the user encounters the conflict.
