Code Review

This pull request introduces a new feature flag, 'macosArm64Only', which configures macOS release and profile builds to target the arm64 architecture only, rather than generating universal binaries. It includes corresponding unit tests and updates to fake test classes. Feedback on the changes identifies a compilation error in 'build_macos.dart' where the 'featureFlags' reference must be prefixed with 'globals.' due to the prefixed import of 'globals.dart'.

Code Review

This pull request introduces a new feature flag, macosArm64Only, to restrict macOS release and profile builds to the arm64 architecture instead of universal binaries. Feedback on the changes points out that specifying platform=macOS,arch=arm64 as the build destination when the flag is enabled can cause xcodebuild to fail on Intel Macs. It is recommended to use the generic destination generic/platform=macOS and rely solely on ARCHS=arm64 to restrict the build architecture, and to update the corresponding tests to reflect this change.

Adding feature flags will require a g3fix.
