feat(versioning): show copied blocks once in version diffs (experimental)

Behind `experimental.blockCopyDiffs` in the collaboration options; it only
changes what a version diff shows. A type change or a move stores a copy
of the block, so the diff showed it as a deleted and an inserted block,
with the copied content credited to whoever made the change. Pair each
copy with its original (by block id) and show it once:

- a type change between text blocks as a formatting change;
- a move, including an indent, as "Moved";
- a copy in the same place (its children changed) as unchanged.

Copied content keeps its authors. Content the earlier version had that no
copy kept still shows as deleted.
