Part of #23043.

Intent is that unless consumer enables disable_old_builder Cargo feature on oxc_ast crate, legacy own methods of AstBuilder should work as before, with minimal breaking changes.

#23875 erroneously changed all the legacy methods from taking self to &self - which is a large breaking change, even without disable_old_builder feature enabled.

Revert that change. It's not required, as AstBuilder remains Copy unless disable_old_builder feature is enabled.

fix(ast): legacy AstBuilder methods take self not &self (#23891)
3800f01 
Part of #23043.

Intent is that unless consumer enables `disable_old_builder` Cargo feature on `oxc_ast` crate, legacy own methods of `AstBuilder` should work as before, with minimal breaking changes.

#23875 erroneously changed all the legacy methods from taking `self` to `&self` - which is a large breaking change, even without `disable_old_builder` feature enabled.

Revert that change. It's not required, as `AstBuilder` remains `Copy` unless `disable_old_builder` feature is enabled.
