Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

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

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.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

The failure mode in the attached crashtest is an inconsistency in the flattened
tree. Specifically, we null out mVideoControls in an nsVideoFrame, but defer
the UnbindFromTree call on that NAC element, which measn that its mParent still
points to the nsVideoFrame's mContent. Because all this stuff runs off of script
runners, and the anonymous content destroyer is not guaranteed to run before
other potential script runners, we end up running arbitrary script while the
tree mismatch exists. This script calls back into ProcessPendingRestyles, which
causes trouble.
We could build a separate deferral mechanism, but it's not clear that we actually
need to defer the unbind anymore. The deferred unbind was added in bug 489008,
which predated a lot of simplifications in layout/dom interaction.

CompareCacheHashEntry::mCrit[] is the only case where the nsXPIDLString-ness
was important. The patch adds an explicit SetIsVoid() call to that class's
constructor and changes some null checks to IsVoid() checks.

nsIFrame::mClass is of type enum class nsQueryFrame::ClassID which is
a strict subset of the nsQueryFrame::FrameIID values. For a concrete
frame class, its FrameIID is the same numeric value as its ClassID.

CreateFrameFor only gets called for frames that get constructed by the special
nsCSSFrameConstructor::CreateAnoymousFrames path
There's nothing special about buttons, so they just take the normal
AddFCItemsForAnonymousContent path. That path actually asserts against
a non-trivial CreateFrameFor implementation, but the assert currently
doesn't fire due to the mismatch between aPossiblyLeafFrame (which is the
nsGfxButtonControlFrame used to generate the anonymous content) and aFrame
(which is the inner block frame passed as the container to
AddFCItemsForAnonymousContent).
I'm not 100% sure that I'm being very consistent in my handling of
mFocusedValue, but since that's not used for file inputs, I don't think it
matters much...
A bigger problem is if people start using this caller type for things other than
file inputs.
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.
