Win32 support
r? @frewsxcv for python stuff
r? @pcwalton for the "remove usage of Gaol" stuff for Win32
r? anybody else for misc cargo.lock updates, etc.
This replaces #7878.
This works best with https://github.com/servo/mozjs/pull/71, too, to enable static linking, but can be run without (via some PATH hackery).
The instructions are here, and will be added to a .md file in the repo once the mozjs changes also land:

I'd like to get these changes landed because I've been rebasing them for months, they're otherwise quite stable, and don't affect our other platforms and targets.

Implement non-zero dimension attribute parsing
Fixes#8445
The only attributes I found that we have implemented that uses non-zero
dimenion attributes:
* `width` for `<td>` and `<th>` (table cells)
* `width` for `<table>`
I updated these implementations to use the new non-zero dimension
attribute parsing and added associated regression tests.

This patch does a number of things, unfortunately all at once:
* Hoists a large subset of the layout wrapper functionality into the style system.
* Merges TElementAttributes into the newly-created TElement.
* Reorganizes LayoutData by style vs layout, and removes LayoutDataShared.
* Simplifies the API for borrowing style/layout data.
There's still more to do to make the style system usable standalone, but
this is a good start.

I don't think there is any reason to keep the container more generic
than its (only) implementation -- the constraints are necessary for this
container to work at all.
Defining the constraints on the type itself also enables use
of #[derive(Debug)].
