pkg/plugin/v3: Use GroupPackageName (the API Group cleaned to be used as

the package name) as the package name when generating
controllers and controller suite test files with
non-empty API groups in MultiGroup projects.
When generating controller with an empty group name in a
MultiGroup project, or when generating a controller in a non
MultiGroup project keep the current behavior, which is
using the `controllers` package name for both the
controllers and controllers suite test files.
