Summary: The `bytes` crate still does not support zero-copy on mmaped buffer. Switch to `minibytes::Bytes` so bytes returned from our main storage backend indexedlog is a zero-copy slice backed by a mmap buffer. Migrate vfs, revisionstore, pyworker to minibytes so they can preserve zero-copy mmap buffers from indexedlog. The edenapi/types is unchanged, since it's also used in Mononoke which uses `bytes::Bytes` all the places. The conversion to `minibytes::Bytes` is cheap so it's probably not a performance issue.
