rust-dirstate-v2: fix the unused bytes counter when rewriting the dirstate
As per the previous patch, the counter was incorrectly carried over from the
old docket when it should be reset for a complete rewrite.

rust-dirstate-v2: show `unused_bytes` counter is not reset on total rewrite
This was picked up by @aalekseyev when doing unrelated debugging.
The Rust implementation was never resetting this counter, so a brand new file
would carry over the old counter.
As I write this, my counter is a supposed 7389089 unused bytes for a total of
170978 bytes in the data file. Feel free to post your own high score.

test-dirstate: use new `--docket` flag to get the data uuid
This is more robust.

debugcommands: remove `debugdirstateignorepatternhash`
This is replaced by the more complete `--docket` option to `debugstate`.

dirstate-v2: add flag to `debugstate` to print docket information
This is useful information that we don't easily have access to currently,
unless you speak fluent xxd.
This replaces `debugdirstateignorepatternshash`, which I'll remove in the next
changeset.

doc: use an absolute path in sys.path to work around a python DLL loading bug
This bug[1] was causing the zstd entry under "Available Compression Engines" to
be omitted from the documentation for some versions of python3. I could
upgrade, but past upgrades have broken venvs and clobbered installed packages.
It's a trivial workaround, so there's no sense in leaving this subtle issue. It
was flushed out by changing the module policy here from 'allow' to 'c', and
seeing this error:
ImportError: DLL load failed while importing parsers: The parameter is incorrect.

rhg: fix dirstate-v2 data file removal system
In D12581 I introduced logic to remove the previous dirstate-v2 data file
after a new one is created (and its corresponding docket), but the logic was
flawed. I fixed it and made it simpler to understand by gather all logic in
a single expression.

rhg: use `Command::exec` instead of `Command::status`
`rhg` is supposed to be a transparent executable, using a subprocess defeats
that purpose. See inline comments for more details.
This also introduces the `which` crate to check if the fallback executable
actually exists to help debugging (plain `execve` doesn't give much
information).
The error code 253 is used to signify that the fallback is not found, but may
mean in the future that it is otherwise invalid if we start being more
specific.
