Add support for bazel run for ios_application with tree artifacts

- Currently only takes effect when this define is specified but I assume will tbe the default at some point `--define=apple.experimental.tree_artifact_outputs=1`

RELNOTES: Add support for `bazel run` for `ios_application` when using tree artifact outputs

Closes #362.
