Support any

[crane-hiromu]

Thank you for creating this library 🤝

Describe the bug

Regarding any, which will definitely be implemented in swift in the future
-> https://github.com/apple/swift-evolution/blob/main/proposals/0335-existential-any.md

We are unable to conduct tests because the code generated by Spyable macro lacks the 'any' attachment on the protocol.
If a new Xcode 15.3~ or flag is turned on...

To Reproduce

When we use

• Xcode 15.3~

or

• -enable-upcoming-feature ExistentialAny flag

Expected behavior

Can run tests

Additional context

We are rewriting mock code using Spyable in a large-scale project.
Your support with this task would be greatly appreciated in the nearly future.
Thanks 👍

Hey there! I see what’s happening with the `any` keyword and Xcode 15.3+. I’m on it and will look into a fix asap. Super grateful for your input. Cheers, Mateusz
