Mac_build_test doesn't prepare iOS device about flutter

[jmagman]

@keyonghan This should only be needed for the test part, not build. Is the recipe the same for both?

Looking at the recipes code, looks like https://flutter.googlesource.com/recipes/+/refs/heads/main/recipes/devicelab/devicelab_test_drone.py is the recipe for the test part

The test part is using a separate recipes, but we may consider consolidating them.
Let me add the preparation logic to the recipe.

The build part doesn't need to happen on a devicelab machine, but in this case the test does.
Is there any work being done to move more tests to build/test?

That's correct.

We are not pushing hard on this direction before we have the graph scheduler, with which the build and test separation will benefit the most. Otherwise, we are just moving the build time from a devicelab testbed to the VM (the execution time even increases more considering the whole orchestrator's waiting time in the whole run)

https://flutter-review.googlesource.com/c/recipes/+/54841 fixes this issue.

@keyonghan Follow up question, is there a reason we run this test in presubmit? I thought we tried to avoid running tests with physical iOS devices in presubmit?
