Fix potential compaction issue in env_copy()
`src_ep[VM_ENV_DATA_INDEX_ME_CREF]` was read out and held without
marking across the allocation in vm_env_new(). In case vm_env_new() ran
compaction, an invalid reference could have been written into
`copied_env`.
It might've been hard to actually produce a crash with this issue due to
the pinning marking of the field in rb_execution_context_mark().
