dirstate-tree: Add a dirstate-v1-tree variant of some tests

The `dirstate-v1` variant has the previous behavior.

`dirstate-v1-tree` uses the same format on disk, but uses the new
`DirstateMap` with a tree data structure and the new `status` algorithm.
These were untested so far.

Differential Revision: https://phab.mercurial-scm.org/D10698

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
