Sami Kyostila 9dbab9bbdb [tracing] Migrate tracing to Perfetto track events ... This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT macros) with the track event base implementation from Perfetto. The advantages of doing this are: 1) This allows us to remove most tracing-related backend code from V8. 2) V8 can start writing strongly typed trace event arguments, which are more compact, easier to process and more extensible than legacy JSON-based trace arguments. For the time being, we still support the old trace macros when V8 is embedded into Chrome and other embedders.
