This is still far from perfect given the limitations of the Storybook web components package, but I figured this was worth putting up since it's still an improvement over the current state of our args tables (I think).

I'm mostly leaving the default generated `custom-elements-manifest.json` alone save for filtering some internal properties we don't want documented since they shouldn't really be accessed directly. If it seems too strange to just have the `aria-label` attr documented we could possibly remove `attributes` from the docs for now (this happens because it's the only attr where the name is different from the property name).

Open to feedback/thoughts on if this is useful or too wonky for now given the weirdness around how Storybook creates naming collisions.

We know that `*.egg-info` directories are cross-platform because they

Bug 1666347 - Delete assorted dead code after removal of vendored `psutil` r=firefox-build-system-reviewers,mhentges

Most of the deletions here come from bug 1481612, the `--with-windows-wheel` option to `mach vendor python`, which according to that commit message "is very single-purpose: it's intended to let us vendor an unpacked
wheel for psutil on Windows". Since vendoring `psutil` is something we're no longer doing, we can safely just delete that added code.

Bug 1588223 - Use many domains in iframes for tabswitch test r=stephendonner,perftest-reviewers,rwood

This adds a tp5n-multiproc output directory which contains postprocessed
versions of the tp5n set. They are processed to take iframes with relative
URLs and output absolute URLs with domains similar to their original
domains. This will help us better simulate a real-world case for Fission,
which will split processes based on the ETLD+1 of the domain.
