The patch introduces a dedicated dispatching class for JIT code events. It is
set as a helper on the isolate.
This allows classes across v8 to break their dependency on Logger and CpuProfiler.
These two became just regular clients of the dispatcher.

This CL adds a TRACE_EVENT where there is an isolated LOG, a HistogramTimer
or a TimerEvent.
Once we have a d8 tracing controller, all TimerEvents will be removed since
they do not provide an added value over TRACE_EVENTs. HistogramTimers will
remain, but their functionality will be limited to Histograms only.

This patch adds the newly added support for contexts in V8 Tracing, as well
as use it to mark all the entry points for a V8 Isolate.

This is based on the Skia Implementation.

The V8 Tracing platform will replace the isolate->event_logger().
But since the current embedders (namely chromium) currently use the isolate->event_logger, I made the default implementation (event-tracer) call into isolate->event_logger if an event_logger was set.
Once the embedders properly implement the interface (for example in chromium it would look like this: https://codereview.chromium.org/707273005/), the default implementation will be doing nothing.
Once the embedders side is fixed, we will change how V8 uses the tracing framework beyond the call from Logger:CallEventLogger. (which would also include a d8 implementation)

This enables linter checking for "readability/namespace" violations
during presubmit and instead marks the few known exceptions that we
allow explicitly.

Replacing it with SMI_ACCESSORS.
This change makes accesses to Smi fields in objects more regular (the
accessors now always consume/return an int rather than a Smi*), which
avoids a bunch of manual Smi::FromInt() and Smi::value() conversions,
and is a step on the way towards being able to generate objects-inl.h.

The preprocessor defines ENABLE_LOGGING_AND_PROFILING and ENABLE_VMSTATE_TRACKING has been removed as these where required to be turned on for Crankshaft to work. To re-enable reducing the binary size by leaving out heap and CPU profiler a new set of defines needs to be created.

In browser (DevTools) mode, only non-native JS code and callbacks are reported.
Also, added "(garbage collector)" entry which accumulates samples count in GC state.
Trying to display "(compiler)" and "(external)" only brings confusion,
because it ends up in displaying scripts code under "(compiler)" node, and DOM
event handlers under "(external)" node, which looks weird.
