convert: update p4 for Python 3
Differential Revision: https://phab.mercurial-scm.org/D10703
tests: change the fixer commands to use the buffer attribute on stdio objects
Otherwise `\r` was getting injected into the fixed lines and throwing off the
commit hashes on Windows when the fixer is invoked with py3.

tests: stabilize test-persistent-nodemap.t on Windows
Several issues here:
- Hooks can't invoke shell scripts on Windows, so use `sh` to launch
- `dd` in MSYS only recognizes `status=noxfer`
- The `PATH` updating triggered a massive slowdown, but is no longer needed
I have no idea why, but removing the `PATH` update substantially increased the
speed of the test. It was running finishing at ~4:30 with `--debug` and ~14:50
without it, but now completes in ~2:20 on my Windows laptop.

tests: invoke some shell scripts through the shell interpreter for Windows
Otherwise, Windows was prompting what program to use to open the file (or just
opening it if there was a file association configured).

tests: run python script through quoted interpreter instead of directly
This helps Windows when python is installed to %PROGRAMFILES%.

tests: ensure `$PYTHON` is quoted for Windows
Global installs of python3 go into "Program Files", and tons of tests fail with
mysterious errors if this isn't quoted. Most of this is a followup to
0826d684a1b5, but a some of these were existing issues. Shebang lines are
ignored because quoting breaks direct execution- these will need to be launched
indirectly with the quoted `$PYTHON` command.

black: make codebase compatible with black v21.4b2 and v20.8b1
I don't know what exact version of black made it care about these whitespace
differences, but this is the version I got when I just installed it with
`pip3 install black`.
I'm intentionally not increasing the version of black required, as I don't want
to force everyone to upgrade their version of black, and these fixes are
backwards compatible with black v20.8b1. If there are more issues in the future
and this becomes a maintenance burden I may do so in a future change.
Tested with both versions of black (I got the older version via
`pip3 install black==20.8b1`)
