When flutter/synchronization was first authored, we did not own fml (it was called fxl then). Now we do, so use a single spot for such utilities. The pipeline was meant to be a general purpose utility that was only ever used by the animator (it even has animator specific tracing), so move that to shell instead (where the animator resides).

The issue with gn --unoptimized seems to be solved in the ToT engine, buildroot, or depot_tools.

The added test makes sure that it won't be broken again for non-Google windows machines.

The number of workers depends on what the platform deem appropriate for the system at runtime.

Some components in the Flutter engine were derived from the forked blink codebase. While the forked components have either been removed or rewritten, the use of the blink namespace has mostly (and inconsistently) remained. This renames the blink namesapce to flutter for consistency. There are no functional changes in this patch.

Creating fonts can take a long time (50ms+) during frame build in the UI
thread.  Trace them to help us understand when it's causing a jank.

When running on Fuchsia, "fml/trace_event.h" sends trace events towards
Fuchsia's tracing system, rather than its own |fml::tracing::*| one.  Do
the same thing for |FlutterEventTracer|, in order to unlock category
"skia" trace events when running on Fuchsia.

The reason this was not working before is because |FlutterEventTracer|
was directly using |fml::tracing::*| functions, rather than the
TRACE_EVENT_* macros.

In the future, we can look into having the skia event tracer enabled by
default on Fuchsia, controlling the presence of Skia events by
enabling/disabling the "skia" category, once we measure the performance
cost of doing so.
