[Bug] Generated mocks not accessible from within #Preview

[ben-fortier]

You can't use a generated mock inside of a #Preview. The workaround is to use a preview struct that conforms to PreviewProvider instead, but it would be nice to be able to use #Preview.

Example:

@Mocked protocol Dependency {
    var value: Int { get }
}
   
   
// even in a new file
#Preview {
    let dependencyMock = DependencyMock() // not found
}

After a quick search, I see that someone else has noted this same issue here. I haven't been able to find any other posts about this issue, but macros are still very new. My guess is that this is a bug with macros, not a bug with Mocked, but we'll have to look into it more.
