**Description:**
Second attempt to enable bytecheck. This PR does not have versioned struct yet, just enabling bytecheck wherever possible. Also, it is for the ast only yet, so transform metadata and others might need this later.
PR seems to be passing all the ci, but as we've experienced before, there might be some unexpected outcomes with the release. Maybe better to hold this until clear https://github.com/swc-project/swc/issues/7238, then land as a separate release.
**Description:**
Another update to enable bytecheck rkyv feature flag.
Our dep tree is quite tangled with implicit enable (plugin -> rkyv). PR tries to detach some of it while trying to preserve existing behavior as much as it can.
