Moved common cross-project functionality out from SkTraceEvent.h into SkTraceEventCommon.h
Traditionally, SkTraceEvent.h was manually kept in sync with base/trace_event/trace_event.h, with project-specific parts intermixed, and tended to drift out of sync a lot (mainly in Blink, less so in Skia).
The SkTraceEventCommon.h now has only the cross-project parts, and can be copy-pasted verbatim between projects (it's an identical copy of base/trace_event/trace_event_common.h), meaning SkTraceEvent.h shouldn't go out of sync as it has before.
