feat(tvix/castore/fs): implement opendir/releasedir r/7915
Similar to how we already handle opening files, implement opendir/
releasedir, and keep a map of dir_handles. They point to the rx side of
a channel.

This greatly improves performance listing the root of the filesystem
when used inside tvix-store, as we don't need to re-request the listing
(and skip to the desired position) all the time.
