New, faster version of protobuf-aware tree shaker was introduced in https://dart-review.googlesource.com/c/sdk/+/152100. It has been used in Flutter use cases for a while. This change replaces old version of transformation with the new one in the pkg/vm/bin/protobuf_aware_treeshaker.dart tool and removes the old version. TEST=existing tests in pkg/vm/test/transformations Change-Id: I01546ae9fdc9fea3228595270c2aff04a0894e6b Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/178281 Commit-Queue: Alexander Markov <alexmarkov@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com> Reviewed-by: Sigurd Meldgaard <sigurdm@google.com> Reviewed-by: Aske Simon Christensen <askesc@google.com>
