This updates to mojo commit d259eb58aa59 and limits the roll script to
only pull in the parts of //mojo that are currently being used. More
stuff will be dropped in the future.
This code was written from scratch for Sky by copying what
linux did, however that doesn't match with the expectations
of the surrounding code. Instead here I just copied what Blink
was doing around this time by looking at:
https://blink.lc/blink/tree/Source/platform/fonts/mac/FontPlatformDataMac.mm?id=f0ab9794a9d1240ce5a57e510fdb82dbc8337906
Blink has since diverged from this codepath, but this at least
makes our FontPlatformData match how the rest of the mac code
expects it to operate. This is all way more complicated than
we need.

The first one is that we weren't setting up a
FontCachePurgePreventer during drawText. It's not clear
that this is the correct fix, since Blink doesn't have
this FontCachePurgePreventer here either, but it's also
possible that they would hit this same ASSERT and just
not care (since ASSERTs are disabled on clusterfuzz).
The second fix is making ExceptionState actually track
whether it has thrown an exception or not. The c++ code
was depending on this working in order to return early
from dom functions and not crash!

- Add missing dependencies caught by gn's new stricter checker
- Update opentype code to use new OTS API. This code is updated from HEAD
Blink.
- Add base dependency to wtf to avoid redefining marcos from base/macros.h
- Update callers of various base string utility functions to use base
namespace.
The primary goal of this change was to remove EventTarget from the
sky_engine C++ code. Since EventTarget is so core to the entire event
system that sky_engine was based on, this is a rather invasive change.
As such, it had some knock-on effects. I deleted some of the files
that were affected, and cauterised the remainder.
In many cases, a file would depend on another file that it didn't
include directly, but instead included indirectly via another file
that I deleted. When this happened, if the features that this broke
were obsolete, I sometimes just removed the features instead.
Specifically:
- removed EventTarget
- removed EventQueue, since without a target, what's a queue going to
do?
- same with EventDispatch*
- removed ExecutionContext, since it had an EventQueue and nothing
else it did was relevant to Sky anymore
- removed ActiveDOMObject, which was all about ExecutionContexts
- removed ContextLifecycleNotifier since it dependend on
ExecutionContext and ActiveDOMObject
- removed the other Lifecycle classes for consistency, and replaced
them with four booleans in the Document class
- removed some of the attributes that are no longer relevant from
IDLExtendedAttributes (ConstructorCallWith and
CallWith=ExecutionContext)
- removed the Document member on DOMDartState since we never set it to
anything but null.
- removed BuiltinSky::InstallWindow since it relied on the Document
member of DOMDartState
- removed EventHandler, EventListener, and mentions of those in
various binding scripts
- removed NewEventHandler, since we're not using that either
- removed the following interfaces from the Sky Dart API:
- EventTarget
- EventListener (since without a target, there's no way to listen)
- FocusEvent (since it's only member was an EventTarget)
- HashChangeEvent (mostly by accident, but it's defunct anyway)
- FontFace (it used ConstructorCallWith=ExecutionContext)
- changed the following interfaces of the Sky DART API:
- MediaQueryList is no longer an EventTarget
- Node is no longer an EventTarget
- Document no longer has defaultView (depended on
DOMDartState's document)
- DocumentFragment, Element, Range, and Text no longer have a
constructor (they all depended on DOMDartState's document, which
is now gone)
- Event lost its EventTarget members and path.
- Window lost its WindowTimers partial interface (it used
EventTarget and ExecutionContext a lot)
- removed numerous hacks in the bindings around features that are now
gone, like addEventListener
- removed a bunch of console logging code, since that relied on
ExecutionContext
- cauterised the wound in FontFace.cpp by removing constructors and
methods that called now-removed features
- same with MediaQuery and friends
- same with some editor features and focus-related features
- same with Document
- removed DOMTimer classes since they use ExecutionContexts
