This patch basically does:
* remove StyleSetHandle and its corresponding files
* revisit #includes of related header files and change correspondingly
* change nsIPresShell::mStyleSet to be UniquePtr<ServoStyleSet>
* change the creating path of ServoStyleSet to pass UniquePtr
* change other mentions of StyleSetHandle to ServoStyleSet*
* remove AsServo() calls on ServoStyleSet
Some unfortunate bits:
* some methods of (Servo)StyleSet only accepts ServoStyleSheet while
many places call into the methods with StyleSheet, so there are many
->AsServo() added to sheets

We flushed the style of the original doc, but not layout, and thus the iframe
resize wasn't noticed, and the style flush on the child presShell wasn't
sufficient.
Do a style flush on the child document instead, so that it flushes layout on the
parent document too if needed.

Summary:
FlushTarget wants to decide whether we should flush the parent document or all
of them. However, the only point of flushing parent documents is that media
query changes could affect the document we really want to flush.
That's completely pointless if we actually don't flush the subdocument, so just
skip doing that. This case is already checked (see the DocumentNeedsRestyle
stuff, which is also somewhat poorly named, which walks up the document chain).

Everyone calls them with the shell of the current composed document, and this
allows the multi-presShell stuff to just be in UpdateCurrentStyleSources /
DoGetStyleContextNoFlush.
The only reason we need to use OwnerDoc()->GetShell() instead of the composed
doc in GetStyleContext / GetStyleContextNoFlush is Element::GetBindingURL, which
does expect to get the binding URL for stuff outside of the composed doc (and
changing that gave me a useless browser).
That's technically a behavior change on the cases that used to pass nullptr, but
I think all callers are fine with that. I could also just add a special function
for that particular case, it may be worth it.

Much in the spirit of bug 1434474.
We right now call MediaFeatureChanges sync or async pretty randomly. This has
caused bugs in the past like bug 1413143.
Unify media feature changes, and only post them async, and flush them from
FlushPendingNotifications.
This also fixes a pre-existing problem where style wasn't flushed correctly from
getComputedStyle when there were pending media feature values.

This change is in response to this CSSWG resolution:
"RESOLVED: compute min-width/min-height: auto to auto"
https://github.com/w3c/csswg-drafts/issues/2230#issuecomment-362009042
...which was later clarified as only being applicable to grid/flex items (in
both axes). Other layout modes may get further min-width/min-height
clarification, but for now we'll leave that behavior the same (returning 0 from
getComputedStyle).

Some Gecko style system files are modified to prevent assertions and
crashing, and to keep test failures on stylo disabled builds to minimum.

This causes the subject principal that was responsible for setting a CSS
property, or the full cssText of an attribute, to be threaded through the call
chain to the point where CSS parsing happens, so that it can be used as the
triggering principal when loading URLs for that property.
Note that this allows for different properties defined in the same style
attribute to have different triggering principals, depending on the caller
which originally set them, as long as the cssText of that attribute is not
modified. Once it is, all properties revert to the principal of the caller
that modified the CSS text.

This is a prerequisite change for passing pseudo element to
Servo_StyleSet_GetBaseComputedValuesForElement which will be done in the next
commit.
