Mitchell Hentges fdc33dac57 Bug 1725895: Port --profile-command to pure-Python r=nalexander,glandium
As part of this, the shell-script part of `./mach` can be removed,
making it pure Python.

There's a change in `--profile-command` behaviour, though: it now only
profiles the specific command, rather than all of Mach.
This is because _so much of Mach_ has already been run before
CLI arguments are parsed in the Python process.

If a developer wants to profile Mach itself, they can manually run
`python3 -m cProfile -o <file> ./mach ...`

This directory contains common Python code.

The basic rule is that if Python code is cross-module (that's "module" in the
Mozilla meaning - as in "module ownership") and is MPL-compatible, it should
go here.

What should not go here:

* Vendored python modules (use third_party/python instead)
* Python that is not MPL-compatible (see other-licenses/)
* Python that has good reason to remain close to its "owning" (Mozilla)
  module (e.g. it is only being consumed from there).
