rust-dirstatemap: inline the last `get_or_insert` call
The `get_or_insert` method was dangerous because it did not take the
`DirstateMap` counters into account. This particular instance does not need
to update the counters.

rust-dirstatemap: add `set_cached_mtime` helper method
This will help remove the `get_or_insert` method, which is dangerous because it
does not take the `DirstateMap` counters into account

rust-dirstatemap: add `clear_cached_mtime` helper method
This will help remove the `get_or_insert` method, which is dangerous because it
does not take the `DirstateMap` counters into account.

rust-dirstatemap: add unit tests
These were missing and have already proven valuable since they have found
two bugs (fixed in previous patches).
There may be other behavior to test, but this gives us a decent coverage.

rust: add `Debug` trait to a bunch of structs
This is useful when... debugging. Right now the output is not in the most
readable state it could be, but this is very low effort and is good enough
for now. We may want to write a nicer custom debug formatter for some of those
structs in the future.

rust-dirstatemap: use `&HgPath` instead of `HgPathBuf` in `copy_map_insert`
No reason to require an owned path here.

rust-dirstatemap: use `DirstateEntry::tracked` directly
`state()` is a legacy API that will be removed at some point, let's use the
newer API.

rust-dirstatemap: remove `set_dirstate_entry`/`set_entry` methods
These methods were needed crutches before the Rust implementation caught up
to Python. Calling `set_entry` (whether from Python or Rust) was dangerous
since it didn't update any of the counters of the DirstateMap data structure,
while having no real way of knowing when to use it "correctly" except it you
were one of the 3 people who looked deep enough into the soul of this code.

rust-dirstatemap: implement part of the `setparents` logic
The Python code does many round-trip calls to the Rust dirstatemap when copy
information needs to be dropped in `setparents`.
This may result in improved performance on `commit`, `update` and other such
commands, but was mostly done to drop the last use of `set_dirstate_item`.
See inline comments for an asterisk about performance, and see next patch for
why `set_dirstate_item` has to go.
