Frame Timeline Perfetto producer

This change adds a Perfetto Producer inside FrameTimeline that emits
DisplayFrame and SurfaceFrame as TracePackets as per the proto defined
in frame_timeline_event.proto
This change also adds a MockFrameTimeline to be used in unittests as a
part of TestableSurfaceFlinger. Due to perfetto capability, running
production FrameTimeline in TestableSurfaceFlinger has caused issues and
its best to isolate them.

Bug: 170914689
Test: libsurfaceflinger_unittest (whole test suite without filter)
