branchcache: use an explicit class for the v2 version
This prepare the introduction of an experimental v3 format version.
In the process, we move the description of the format in that new class.
test sparse with --verbose and -T json

Verifying that problematic files still allow us to see the deltas when forcing:
$ hg debugsparse --include 'show*'
$ touch hide
$ hg debugsparse --delete 'show*' --force -Tjson
pending changes to 'hide'
