From: Kevin Cheng <kevin.cheng@arm.com>
Date: Thu, 14 Oct 2021 11:53:39 -0700
Subject: Both serializer and schema carry version info now

- version number now encoded in serializer as well
- rename experimental to draft
- rename internal function from FreezeBuilder/InitWithBuf to Serialize/Deserialize
