refactor(ast): estree via on struct fields implement From

[overlookmotel]

Align the behavior of custom serialization to ESTree using the #[estree(via)] attribute. Change its behavior on struct fields to match structs - the "via" type must implement From to convert from the original type to itself.

The future goal is to use these same "via" types to go back in the other direction (JS -> Rust), so we need to have a casting system.
