Implement DocumentFragment XML serialization.
When serializing a DocumentFragment node, we should follow [this guy](https://w3c.github.io/DOM-Parsing/#dfn-xml-serializing-a-documentfragment-node) and serialize the node's immediate children. This commit makes that change.

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.
