WIP - Expose API to pick SharedTree persisted format version

[alexvy86]

Description

Proof of concept of a way in which we could expose the SharedTree persisted format version so users could choose which one to use. Maybe this approach does a bit more work than necessary (exposing configuredSharedTree() as @alpha instead of @internal might be ok, although that exposes more options than just the persisted format version).

Reviewer Guidance

The review process is outlined on this wiki page.

One thing that feels particularly tricky to me is that the single format version gets mapped internally to multiple codec versions for different parts of SharedTree, and not all of them necessarily get exercised at the time we load the container (the one for loading the summary does, for example; but the one for ops might not... unless there are trailing ops; not entirely sure what the others are for). So ensuring a) that we fail when any version mismatch is encountered (under the assumption that we expose the format very conservatively to begin with, in a "only work with this version" way) and b) quick enough so that the container cannot be used at all in case of mismatch, seems potentially complicated and brittle.
