This change adds the simplest kind of incremental layout. When Servo
detects that all style changes only require a repaint, only run stacking
context tree and WebRender display list generation. This means that
these kind of restyles do not need a re-layout. Instead, the existing
box and fragment trees will be used and the styles of damaged nodes will
be updated in their box and fragment tree nodes.
This requires a new style repair DOM traversal for nodes that have had
their style damaged. In addition, careful accounting of all the places
where we store style must happen in order ot update those styles.
Testing: This is covered by existing WPT tests as it should not change
observable behavior.
We have created a test case which shows a 50% speedup when run
in Servo, even though there still a long way to go to match the speed
of other browsers:

To be able to abort the update, extract the functionality into a
separate method. Otherwise, we don't run the `node.rev_version` at the
end, which according to the comment is probably important.
Not all `style-src` tests pass and I don't fully understand why yet, but
I presume it has to do with some special quirks of stylesheets that
other CSP checks don't have. All `style-src-attr-elem` tests pass
though.

As a follow-up to the recent introduction of `script.src`
as trusted sink, this PR refactors machinery to also
support `TrustedScript`. In doing so, all trusted sinks
in `HTMLScriptElement` are now covered.
Instead of calling the callbacks in `policy.createX`,
we now have a `TrustedType` enum that specifies which callback
to invoke. Unfortunately we still have the `USVString` vs
`DOMString` problem, which is why we need to `.map` twice
to retrieve the backing `String` and avoid two different
types.
Additionally, I saw that `script.text` should have called
the "String replace all" algorithm rather than setting the
child contents. So that's also now fixed.

This macro does not hide any complex or unsafe implementation details,
and, it's only used in two files (node.rs and element.rs). This patch
removes the macro, and move the implementation in place.
Moreover, the Element::rare_data_mut function in element.rs is called by
other functions, so the #[allow(dead_code)] annotation is removed. The
Node::rare_data_mut function in node.rs is not called anywhere, so it is
removed.
