Updates `./mach bootstrap` to use `--no-interactive` from global args.
Ensures all bootstrap prompts have a default option.

This code is generally missing tests, but I tried it out on the wpt-sync
where it's used and with this fix it worked (previously it had broken
because the wpt libraries started to assume Py 3 semantics)

Shortly after mach was introduced, bug 840588 turned mach into a small
wrapper that could be copied in a directory part of $PATH, making that
wrapper load the right thing from the right source directory.
Years later, that setup is not really supported, and it's extra
complexity that can lead to unpleasant surprises.

Catch additional cases where both __PYVENV_LAUNCHER__ is set and we invoke a
virtualenv python by unsetting the variable in a prominent location.
This will specifically catch the `./mach bootstrap` => `./mach artifact` case.

It's not 100% clear how long this command will live, but it doesn't look
immediately removable, and it was easy to add python3 support.

This command appears to work just fine under python3 already -- I removed it from the py2 list and ran it with various options, and they all worked fine.

The former is a POSIX shell construct, usually a builtin, and the latter
is an external program that is not guaranteed to be available.
When `which` is not available, a full ./mach build succeeds with this
change.

Minor fix to remoteautomation.py: Increment stdoutlen before any type conversions,
to ensure that it accurately reflects the byte offset in the file.
With this last change, 'mach mochitest' appears to run correctly on Android with Python 3:
switch it over to Python 3.

Since `install-moz-phab` is meant to simplify the moz-phab setup flow,
automatically prompting for Phabricator credentials removes an otherwise
manual step.
Detecting the "console_script" location of a package in a
cross-platform, virtualenv-supporting and "--user"-supporting way is
tough, and the most consistent solution seems to be to list the package
contents of moz-phab and look for the one that seems to be the entry
point.

This is only useful for `mach` commands that we want to run with Python 3 by default, but for which running with Python 2 is still useful. We now have one such command: `python-test`.
In `mach`, switch on the presence of the `MACH_PY2` environment variable. We only want to allow this for `python-test`, so do that sanity check in `mach` as well.

In two different places we've been encountering issues regarding 1) how we configure the system Python environment and 2) how the system Python environment relates to the `virtualenv`s that we use for building, testing, and other dev tasks. Specifically:
1. With the push to use `glean` for telemetry in `mach`, we are requiring (or rather, strongly encouraging) the `glean_sdk` Python package to be installed with bug 1651424. `mach bootstrap` upgrades the library using your system Python 3 in bug 1654607. We can't vendor it due to the package containing native code. Since we generally vendor all code required for `mach` to function, requiring that the system Python be configured with a certain version of `glean` is an unfortunate change.
2. The build uses the vendored `glean_parser` for a number of build tasks. Since the vendored `glean_parser` conflicts with the globally-installed `glean_sdk` package, we had to add special ad-hoc handling to allow us to circumvent this conflict in bug 1655781.
3. We begin to rely more and more on the `zstandard` package during build tasks, this package again being one that we can't vendor due to containing native code. Bug 1654994 contained more ad-hoc code which subprocesses out from the build system's `virtualenv` to the SYSTEM `python3` binary, assuming that the system `python3` has `zstandard` installed.
As we rely more on `glean_sdk`, `zstandard`, and other packages that are not vendorable, we need to settle on a standard model for how `mach`, the build process, and other `mach` commands that may make their own `virtualenv`s work in the presence of unvendorable packages.
With that in mind, this patch does all the following:
1. Separate out the `mach` `virtualenv_packages` from the in-build `virtualenv_packages`. Refactor the common stuff into `common_virtualenv_packages.txt`. Add functionality to the `virtualenv_packages` manifest parsing to allow the build `virtualenv` to "inherit" from the parent by pointing to the parent's `site-packages`. The `in-virtualenv` feature from bug 1655781 is no longer necessary, so delete it.
2. Add code to `bootstrap`, as well as a new `mach` command `create-mach-environment` to create `virtualenv`s in `~/.mozbuild`.
3. Add code to `mach` to dispatch either to the in-`~/.mozbuild` `virtualenv`s (or to the system Python 3 for commands which cannot run in the `virtualenv`s, namely `bootstrap` and `create-mach-environment`).
4. Remove the "add global argument" feature from `mach`. It isn't used and conflicts with (3).
5. Remove the `--print-command` feature from `mach` which is obsoleted by these changes.
This has the effect of allowing us to install packages that cannot be vendored into a "common" place (namely the global `~/.mozbuild` `virtualenv`s) and use those from the build without requiring us to hit the network. Miscellaneous implementation notes:
1. We allow users to force running `mach` with the system Python if they like. For now it doesn't make any sense to require 100% of people to create these `virtualenv`s when they're allowed to continue on with the old behavior if they like. We also skip this in CI.
2. We needed to duplicate the global-argument logic into the `mach` script to allow for the dispatch behavior. This is something we avoided with the Python 2 -> Python 3 migration with the `--print-command` feature, justifying its use by saying it was only temporarily required until all `mach` commands were running with Python 3. With this change, we'll need to be able to determine the `mach` command from the shell script for the forseeable future, and committing to this forever with the cost that `--print-command` incurs (namely `mach` startup time, an additional .4s on my machine) didn't seem worth it to me. It's not a ton of duplicated code.
