This patch declares a new default action, "horizontal scroll", this scrolls
content horizontally with deltaY of wheel events and ignores deltaX and deltaZ.
This is used for default action with Shift key in default setting except on
macOS. On macOS, legacy mouse's vertical wheel operation with Shift key causes
native horizontal wheel event. Therefore, we don't need to use this new
default action on macOS. Additionally, old default action with Shift key,
navigating history, is moved to with Alt key. This makes same settings between
macOS and the others. So, this is better for users who use macOS and another
OS and web app developers who check wheel events only on macOS or other
platform(s).
For simpler implementation, default action handlers moves deltaY values to
deltaX values temporarily *only* while they handle wheel events. This is
performed by AutoWheelDeltaAdjuster and restored after handling it
automatically.
So, in other words, even if default action is "horizontal scroll", web apps
receives wheel events whose deltaY is not zero but its content will be
scrolled horizontally. This is same as Chromium, so, this behavior shouldn't
cause any incompatible behavior with it.

This code lost a landing race with bug 1403868 and so got left behind.

This allows a bunch of additional stuff to be removed: ContextStateTracker,
ContextStateTrackerOGL, and GPUMarkerPayload.

Because it just doesn't control any behaviour within the profiler, and it just
duplicates gfxPrefs::LayersDumpTexture().
With this gone, PROFILER_FEATURE_ACTIVE can also be removed.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.
This patch does the following.
- Makes the TracingKind argument non-optional.
- Puts the UniqueProfilerBacktrace argument last in the second variant.
- Reorders AutoProfilerTracing to match the order of the profiler_tracing()
declarations.
