app/internal/window,cmd/gogio: [iOS] export GioViewController

The Gio GioAppDelegate created the GioViewController programmatically.
When using gogio's -buildmode=archive users may want to use a different
method (for example storyboards) but there can only be one app delegate.

Move the GioAppDelegate to gogio's exe buildmode, and export the
GioViewController for embedding use.
