* Revert "Revert "Reduce xcodebuild noise #2" (#14641)"
This reverts commit 2d47481f1e.
* Stop scrapping xcodebuild output, get the right build settings
* clone the command params first
* Plumb a --strong option through to the front end server and the engine
so that we can run flutter apps in preview-dart-2 and strong mode
* - Address analyzer lint issues
*- correctly set up strong mode option in the case of AOT builds
* Before tests
* Add the part to trust the cert on the device
* flip the error checks since some are more specific and are more actionable
* add tests
* review
The very first time `pod install` is invoked, CocoaPods downloads the master spec repository, which takes quite a while. Before this change, the build appeared to have stalled. With this change, at least the spinner is moving.
Added `pod setup` to the install instructions for CocoaPods, so the spec repo is downloaded while setting up Flutter, instead of during the first build.
Artifacts are now located in a central place.
This will enable us to downlaod artifacts when we need them (instead of
downloading them all upfront).
This also makes replacing sky_snapshot with gen_snapshot easier.

* convert commandValidator to throw ToolExit for non-zero exit code
* convert flutter commands to throw ToolExit for non-zero exit code
* use convenience method throwToolExit
* only show "if this problem persists" for unusual exceptions
* refactor _run to runCmd
* replace requiresProjectRoot getter with call to commandValidator
* replace requiresDevice getter with call to findTargetDevice
* trace command requires a debug connection, not a device
* inline androidOnly getter
* rename command methods to verifyTheRunCmd and runCmd
* move common verification into BuildSubCommand
* rename deviceForCommand to device
* rename methods to verifyThenRunCommand and runCommand
Fix some legit uses of GlobalKey to specify the type they want.
Fix some sketchy uses of GlobalKey in tests to fake it with "as
dynamic".
Remove some extraneous imports that made the build red.
