[vm] Build a runnable Fuchsia package containing Dart
Everything in the build/fuchsia director (except for tests.cmx) was copied and modified from: https://fuchsia.googlesource.com/samples/+/refs/heads/master/build This doesn't include any tests yet, but its runnable on the emulator. Change-Id: Id64ae71062447c789ca4d10ed3a4a09e0a6d7b99 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/152589 Reviewed-by: Siva Annamalai <[email protected]> Reviewed-by: Ryan Macnak <[email protected]> Commit-Queue: Liam Appelbe <[email protected]>
