[deps] Roll native_assets_cli to internal import
https://dart-review.googlesource.com/c/sdk/+/346761 can't land,
because then flutter_tools in g3 breaks.
flutter_tools in g3 can't be forwarded because
https://github.com/dart-lang/native/pull/886 isn't in g3 yet.
Landing https://github.com/dart-lang/native/pull/886 in g3
should work, because it shouldn't break flutter_tools.
