    cppgc: Add tracing scopes · 6a1a3a10
    Omer Katz authored
    This CL adds tracing scopes for the various cppgc classes.
    Scopes use TRACE_EVENT_BEGIN and TRACE_EVENT_END macros to report trace
    events. To do so they need to include trace-event.h. For unified heap
    builds, trace-event.h forwards to v8's src/tracing/trace-event.h. For
    other builds, trace-event.h provides a subset of
    src/tracing/trace-event.h that covers just the parts used by cppgc.
    
    This CL covers what we need for traces and blink gc metrics (up to
    renaming events from BlinkGC.* to CppGC.*). UMA and UKM are not yet
    handled.
