Changed the Requests/Response from tuples to named struct variants and also sorted in alphabetical order.
Replaced the ID generator functions from `globalscope` with a single function,
which returns a `RefMut` and can call the appropriate method to generate resource IDs.

Avoid accessing global objects from DOM destructors
This removes all instances that I could find of DOM objects accessing `self.global()` in code that runs as part of a Drop method. This is unsafe because the GC could destroy objects in any order when doing a big sweep. Instead, these types should store the data they need as members so they can run in isolation without accessing the rest of the GC graph as part of their destructors.

Stop iframes from including their ancestors
An iframe that included itself would just keep loading until running out of resources; the spec includes protection against that, and now Servo follows (some of) the spec about it.

Layout viewer for layout 2020
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
This PR makes layout 2020 dump the box and fragment tree states into json files that can be visualized with the layout viewer tool. This tool has not much functionality other than displaying these trees and allowing to inspect each node additional data, so there is a lot of room for improvements. Some ideas for follow-ups:
- Make the tool create and display diffs between tree states.
- Actually allow creating new debug scopes during box tree and fragment tree construction. Right now there is a single scope created after constructing both trees, which is not ideal as it only allows looking at the reflow result.
- Right now an independent JSON file is created per reflow. It would be nice to unify the data obtained on each reflow on a single JSON, so diffs between reflows can be displayed as well.
- Dump and display the DOM tree. Link boxes to DOM nodes.

Delay reftest screenshot while WR frame is rendering
This PR addresses the theory that #24726 occurs when WR is performing an async frame render and the reftest screenshot decides it's time to synchronously read the framebuffer. If there have not been any completed frames rendered yet, that would yield the page background colour.
The changes in this PR introduce an additional layer of synchronization - the compositor stores an AtomicBool value that indicates whether we know that a WR frame has started rendering, which is set to true when an IPC request from layout that submits a new display list is received. This bool is set to false when WR notifies us that a frame has been rendered. The screenshot code refuses to take a screenshot if the bool is true, causing us to delay taking a screenshot until there is no frame pending.
