refactor(ast_macros): simplify code

[overlookmotel]

Pure refactor. Simplify implementation of #[ast] proc macro.

reorder_struct_fields can mutate the fields of the ItemStruct in place, rather than taking the fields out, altering them, putting them back in, and then converting to a TokenStream.

Pull Request Overview

This PR refactors the #[ast] proc macro implementation to simplify the code structure. The main purpose is to make the reorder_struct_fields function mutate the ItemStruct in place rather than using a more complex approach of extracting fields, modifying them, and reconstructing the struct.

• Eliminated unnecessary std::mem import and mem::replace usage
• Changed reorder_struct_fields to mutate the struct in place instead of returning an Option<TokenStream>
• Simplified the control flow by removing the need to handle None return values
