Reduce binary sizes by removing derived macros which is unnecessary in production

[hyf0]

To support writing test config in json format we add Deserialize, JsonSchema on BundlerOptions. So they are only for rust testing. Users of rolldown doesn't rely on these features.

https://github.com/rolldown/rolldown/blob/e39ddd845ac5ade81cdf1a2b8e0588c3eaf70f9b/crates/rolldown_common/src/inner_bundler_options/mod.rs#L14-L16

However, these test-only feature are compiled and increased the binary size. We don't want that. So we need hide these features using feature gate.
