It could be used to have mutable JSVal fields without GC barriers.
With the removal of that trait, MutHeap and MutNullableHeap can respectively
be replaced by MutJS and MutNullableJS.
Report panics using the top-level frame id rather than the pipeline id
<!-- Please describe your changes on the following line: -->
At the moment, we report panics from script and layout using the root pipeline id. Once we are sharing more script threads, there won't be a root pipeline id any more. The plan is only to share script threads in the same tab, so there will be a top-level frame id that all the pipelines have in common. This PR reports panics using that top-level frame id.
This mostly makes a difference to the browser API: rather than targeting a `mozbrowsererror` event at the root iframe of the script thread that panicked, it targets it at the containing mozbrowser iframe.

Move the `check_and_scroll_fragment()` method into Document, make the
mothod set the fragment of url after navigation, and use the
`perform_a_scroll()` method to scroll rather than an individual
method. Also removes the broken `Window.fragment` fields.
Free-standing fonctions parse_html and friends are now static methods
on ServoParser, and the HTML and XML tokenizers have been moved to private
submodules.
Script thread with no root document
<!-- Please describe your changes on the following line: -->
This PR removes the single root document from the script thread, and replaces it by a lookup table from `PipelineId`s to `Document`s. This is needed if we're going to share script threads, as per #633.
The last commit is the one that matters, the ones before are #13646.

Script lookup iframes by frameid
<!-- Please describe your changes on the following line: -->
Lookup iframes by `FrameId` rather than `PipelineId`. This should make lookup much more reliable, since the frame id doesn't change.

Layers were a feature of the legacy drawing path. If we re-add them at
some point, it probably makes more sense to make them a product of
display list inspection.
This change also remove a bunch of dead painting code.
