flutter run should detect that targeted iOS devices are unpaired and prompt for how to fix #144447
Description
When I unpair my phone (in phone settings Developer > Clear Trusted Computers) and run flutter devices or doctor I see:
Error: iPhone is not paired with your computer. To use iPhone with Xcode, unlock it and choose to trust this computer when prompted. (code -9)
However that doesn't seem to be checked during flutter run and it totally compiles the app, and eventually fails with a generic "can't launch" message:
Could not run build/ios/iphoneos/Runner.app on iPhone.
Try launching Xcode and selecting "Product > Run" to fix the problem:
open ios/Runner.xcworkspace
Installing and launching... 71ms
Error launching application on iPhone.
Ideally it would detect the phone is not paired first and give the nicer error message.
