Bug 1731836: Simplify `./mach python` arguments r=ahal
`--no-virtualenv` was needed for one use case: the `get_and_diffoscope` task, despite not needing `psutil`, would run into failures during virtualenv-creation because we used to unconditionally build the `psutil` package, and `get_and_diffoscope` didn't have the environment needed for such a build. Since we no longer build and install `psutil` into every virtualenv, it's no longer needed for its one usage, which means that it can be removed. `--requirements` is replaced by `--virtualenv`, which removes an ad-hoc pip package installation and embraces the centralized dep system. `--no-activate` is now implied by default: a virtualenv is only created and activated if `--virtualenv` is provided.` `ipython==7.16.1` was the chosen version because it is the last one compatible with Python 3.6.
