Validate build configuration during Xcode build phase (#169395)
You can run iOS/macOS Flutter apps through either the Flutter CLI or
Xcode. However, it's often required to first run the Flutter CLI to
generate required files and settings. Some of these settings/files (like
dev dependencies) are specific to the build mode. However, you can
change the build mode through Xcode too. When you change the build mode
through Xcode, the Flutter-generated files and setting may not be
correct.

This PR checks if the current build mode matches the one last used by
the Flutter CLI. If it doesn't, it'll print a warning like this:

If the build action is `install`, which indicates the app is being built
for distribution, this will print as an error and fail the build:

This directory contains tools and resources that the Flutter team uses during the development of the framework. The tools in this directory should not be necessary for developing Flutter applications, though of course, they may be interesting if you are curious.

The tests in this directory are run in the framework_tests_misc-* shards.
