This avoids having to support storing refcounted URLValue objects in shared memory,
which would be tricky.
Depends on D17183

UA style sheets only ever specify a single generic font family in font-family
properties, so we pre-create a unique, static SharedFontList for each generic
and change the representation of FontFamilyList to be able to refer to them
by their generic ID. This avoids having to share refcounted SharedFontList
objects across processes.

Each user agent style sheet has a unique URLExtraData object containing
its URL, but since they are refcounted objects, we can't share them
easily across processes. Rather than adding support for copying them
into a shared memory buffer like we will do with the Rust objects, here
we just set up a static array of URLExtraData objects per UA style
sheet. The array will be filled in in a later patch.
Rust UrlExtraData objects, once they are transformed into their
sharable form and copied into the shared memory buffer, will reference
them by an index.

This makes `Document::GetShell()` return `PresShell*` instead of `nsIPresShell`.
Additonally, "shell" is unclear ("docshell" vs. "presshell"). Therefore, this
also renames `Document::GetShell()` to `Document::GetPresShell()`.
Similarly, some other method names of `Document` are also renamed from
`*Shell*` to `*PresShell*`.

They're only used in forms.css, and only for some anonymous content, which are
not content-accessible in the first place.
The only place where this could be exposed is calling
getComputedStyle(input, "::placeholder"), so I think this should be pretty safe,
but I've added a pref just in case.
While at it, also derive the Parse implementation. Less code is better.

Promise constructor
In this PR, measures are taken that prevent the ```Promise::new``` constructor from being used outside a compartment.

Add XRFrame.getPose()
I think I've figured out the model of poses, waiting on Nell for confirmation.
Basically, `getViewerPose(p)` is equivalent to `getPose(source=viewerSpace, relative_to=p)`
The eye-level space, for example, is stationary and stuck to the origin. The position-disabled and identity spaces somewhat counterintuitively follow you around (and appear to be stationary from `getViewerPose()` but not `getPose()`.
The incorrect mental model kinda "works" when looking at only `getViewerPose()`, but we need to figure it out for `getPose()`.
Todo (may add to this PR, but probably not)
- implement `XRSession.viewerSpace`
- implement position-disabled
- implement floor-level (hard to test without a 6dof device)

Remove compound microtasks
We handled compound microtasks as microtasks so, basically, we only need
to remove the naming of `compound`.

Users are supposed to use `view.transform.inverse.matrix`
The view matrix was incorrect anyway, we had forgotten to invert it, but that was okay since we transposed it by accident (due to euclid's use of the row-vector convention), and for 3DOF devices these transforms are mostly rotations so transposing instead of inverting doesn't lead to visible effects.
