feat: add macOS platform support (#299)

* add macos platform with `flutter create`

* add build configurations for flavors

* add bundle id suffixes for build configurations

* add and configure AppIcons (copied from ios xcodeproj)

* fix AppIcon set names for dev & stg

* add shared xcode schemes for each flavor

* set app bundle identifier by flavor, and set app window title to Very Good Core (hardcoded)

* remove unintended changes to ios xcode proj/assets

* fix for window name based on flavor
