Adding validation to the generated swiftinterface

[dcacenabes]

I have discovered hidden in the Swift Bugs page a mention to a flag that validates the swiftinterface for a module after generating it added in Swift 5.4:
-verify-emitted-module-interface
"Swift 5.4 supports a -verify-emitted-module-interface flag which causes it to immediately typecheck .swiftinterface files after emitting them to verify that they are valid. You can add that flag to OTHER_SWIFT_FLAGS to make sure your interfaces are readable."
https://bugs.swift.org/browse/SR-14195

What do you think about including this flag as part of this plugin? For our use case this could be cool, because it would prevent our CI from deploying a new private XCFramework with a broken interface and then having to revert the publication.

On another hand, we are also using some other flags like: -Xfrontend -module-interface-preserve-types-as-written
Which are your thoughts about adding to the plugin the possibility of specify flags in general?
