dirstate-tree: Use HashMap instead of BTreeMap
BTreeMap has the advantage of its "natural" iteration order being the one we need
in the status algorithm. With HashMap however, iteration order is undefined so
we need to allocate a Vec and sort it explicitly.
Unfortunately many BTreeMap operations are slower than in HashMap, and skipping
that extra allocation and sort is not enough to compensate.
Switching to HashMap + sort makes `hg status` 17% faster in one test case,
as measure with hyperfine:
```
Benchmark #1: ../hg2/hg status -R $REPO --config=experimental.dirstate-tree.in-memory=1
Time (mean ± σ): 765.0 ms ± 8.8 ms [User: 1.352 s, System: 0.747 s]
Range (min … max): 751.8 ms … 778.7 ms 10 runs
Benchmark #2: ./hg status -R $REPO --config=experimental.dirstate-tree.in-memory=1
Time (mean ± σ): 651.8 ms ± 9.9 ms [User: 1.251 s, System: 0.799 s]
Range (min … max): 642.2 ms … 671.8 ms 10 runs
Summary
'./hg status -R $REPO --config=experimental.dirstate-tree.in-memory=1' ran
1.17 ± 0.02 times faster than '../hg2/hg status -R $REPO --config=experimental.dirstate-tree.in-memory=1'
