...except for clang-format, because versions after v13.0.0 have
borked the Whitesmith formatting. Also moves yapf from
pre-commit/mirrors-yapf to google/yapf.
We also add a very basic yapf configuration file. Most of the changes in
this patch were performed automatically, but we broke one overly long
string into multiple components on `src/make_dbg_constants.py`.
* origin/topic/struck/BIT-1277:

BIT-1277 #merged
- Give Dir::monitor() a param for the polling interval, so different
dirs can be monitored at different frequencies.
- Fix race in Exec::run() when reading extra output files produced by
a process -- it was possible for Exec::run() to return before all
extra output files had been fully read.
- Add test cases.
