This commit adds documentation explaining that there is is no zero-copy way to create a Swift `String`. We also add documentation explaining that the reason the `RustString` type exists is to avoid the implicit allocation that would be required if we automatically converted Rust's `std::string::String` to Swift's `String`. We also document some potential new attributes that would allow users to opt into automatically converted from a `Rust std::string::String` to a Swift String.
