ConstantReader.revive cannot revive constant fields with a type not defined in the same library as the field

[natebosch]

For instance trying to revive from

@Foo.foo
class Foo {
  static const foo = Deprecated('argument');
}

When we search for potential fields which define this argument, we only search the library that defines Deprecated), and of course never find a field equal to our object.

source_gen/source_gen/lib/src/constants/revive.dart

Line 68 in 4dc8f1f

for (final type in origin!.definingCompilationUnit.types) {

If we could know to search the library defining Foo we'd find it.
