changing-files: add a utility to compute the merged files post-commit
We will need it in `_getsidedata` as soon as we start persisting that set.

changing-files: record merged files at commit time
The data is easy to gather at commit time, and we need it for changeset centric
copy tracing. Right now, it is not persisted so we cannot use it. However we
will fix this part very soon, gathering something to persist was necessary
first.

changing-files: add the ability to track merged files too
The set of merged files is used when doing changeset centric copy tracing (cf
`is_merged` in `mercurial/copies.py`. So tracking (and persisting) this set will
be useful. We start with adding the attribute on the new object.

rust: start plugging the dirstate tree behind a feature gate
The previous patch added the `dirstate-tree` feature gate to enable the two
dirstate implementations to co-habit while the tree-based one gets better.
This patch copies over the code that differs, be it because the algorithm
changed or because the borrowing rules are different.
Indeed, `DirstateTree` is not observationally equivalent to the std `HashMap` in
the APIs we use: it does not have the `Entry` API (yet?) and its iterator
returns owned values instead of references. This last point is because the
implementation needs to be changed to a more clever and efficient solution.

rust: introduce `dirstate-tree` cargo feature
This feature gates (at compile-time) the use of the newly-added dirstate tree.
The motivation for this is that the dirstate tree is currently *very* slow;
replacing the current hashmap-based dirstate is not a viable solution in terms
of performance... and why would you be using the Rust implementation if not
for performance?
The feature will also help reviewers better understand the differences that
will slowly appear as the dirstate tree gets better.

rust: fix formatting
Maybe there is a small divergence in the nightly formatter? This didn't seem to
trip the CI.
