This patch does the following things:
* Create a new class ServoFontFaceRule for CSSOM of @font-face rule
which mostly follows how nsCSSFontFaceRule was implemented.
* Remove the old nsCSSFontFaceRule and binding code to create it.
* Have FontFace backed by Servo data via making mRule and mDescriptors
of the class hold RawServoFontFaceRule like ServoFontFaceRule.
To keep this patch small, it effectively just delays the conversion
from Servo data to nsCSSValue from parsing to using. This may cause
worse performance if the font set is flushed repeatedly. Supposing we
don't flush font set very frequently, it may not be a big deal.
We may still want to remove the intermediate nsCSSValue conversion at
some point, and have everything converted to their final form directly
when used, but that can happen in followups.
There are some unfortunate bits from this change:
* We lose style sheet for logging in FontFaceSet. This is probably not
all that worse, because we wouldn't have that before either if the
page doesn't use CSSOM to visit it. But we should figure out some
approach to fix it anyway.
* InspectorFontFace no longer shares the same rule object as CSSOM.
This isn't really a problem if the @font-face rule isn't very mutable.
Unless we want to make the rule returned from InspectorFontFace to be
mutable (i.e. via inspector), not using the same object probably isn't
too bad.
This patch switches the code we use to serialize stuff in FontFace and
CSSFontFaceRule, which leads to some failures in tests. Specifically,
the expected changes including:
* Value of font-family now can be serialized to identifier sequence like
font-family property. The old code always serializes it to string,
but it doesn't seem to have different requirement than the property.
Blink can serialize to identifier as well.
* Family name inside local() is also changed to use the same way as
family names elsewhere (i.e. can be identifier sequence). Blink has
the same behavior as the old code, but I don't think it's a big deal.
* The order of descriptors serialized gets changed. I don't think it
matters at all.
* Empty string as font-family via using string syntax is no longer
considered invalid for FontFace. I don't find it is mentioned anywhere
that it should be specifically treated invalid.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

The PostTraversalTask does not take a strong reference to the FontFace
object, since as a DOM object, we can't call AddRef/Release on it
from the Servo style worker threads. The FontFace objects that we
encounter are all held on to by the FontFaceSet, and none of the
work that we do during font loads should drop FontFace objects
from the FontFaceSet. (That only happens under
nsIDocument::FlushUserFontSet, which is only called on the
main thread.)

This patch is generated by the following commands (note: if you're running
using OS X's sed, which accepts slightly different flags, you'll have to
specify an actual backup suffix in -i, or use gsed from Homebrew):

| xargs -0 -P 8 gsed --follow-symlinks 's/\bnsCSSProperty\b/nsCSSPropertyID/g' -i''
Then:

nsCSSProperty.h.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
