bytecheck
Atom
**Description:** This PR changes the size of `Atom` type to `usize` from 2 * usize`. **Related issue:** - https://github.com/swc-project/swc/issues/4946.
**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.
