Simplify and unify compositor shutdown code paths
Unify all compositor shutdown code paths into two methods, one which
starts the shutdown and the other that finishes it. This simplifies the
way the compositor shuts down and prevents "leaking" pixmaps when
exiting in uncommon ways.

Remove constellation round trip for subpage mapping in compositor.
This makes use of the new functionality that allows iframes to generate their own pipeline IDs in order to remove any knowledge of subpage ids from the compositor.
(This is the first of several commits removing subpage from parts of servo).

Move code to exit servo after writing a screenshot out of composite_specific_target.
The structure of this function was confusing, so move some parts out into the
caller where they seem like a more natural fit and add documentation of the
functions

Make sure to correctly destroy old layers in collect_old_layers_for_pipeline.
The previous code would skip calling clear_all_tiles(), which led to a
panic in rust-layers. ("You should have disposed of the pixmap properly
with destroy()! This pixmap will leak!")
Ran into this messing around with pdf.js; no minimized testcase.
Maybe related to #7895.

Use the correct IDL setter for <font>.size
Previously, the IDL attribute would incorrectly set the `size` attribute
for `<font>` elements as `AttrValue::String`. Now it correctly sets it
as `AttrValue::Length`. Also included is a regression test.

Add an option to dump the layer tree, which activates the previously
unused layer tree debugging code. Also improve the output using the
PrintTree struct.
layout: Add a field in the display list for simple border radii on box shadows.
Only supported in WebRender (with my upcoming PR) for now.
