Pull Request Overview
This PR refactors the oxc_ast_tools code generation to produce variants by parsing the source text multiple times instead of parsing once and cloning the AST. While this is less efficient, it enables modification of source text before parsing, which supports future work in #14681.
Key Changes:
- Replace AST cloning approach with repeated parsing for each variant
- Generate flag constants with appropriate boolean values before each parse
- Simplify the variant generation flow by using an iterator-based approach

In `oxc_ast_tools` codegen, generated variants of code by parsing source text multiple times, instead of parsing once and then cloning AST. This is a deoptimization in itself, but allows modifying the source text prior to parsing, which is useful for #14681.
