Reland: Add trace event Pepper API

This facilitates adding trace data to chrome://tracing from plugins.

- broke out trace_event.h into trace_event.h/trace_event_internal.h
  for easier transplanting to plugin code by eliminating dependence on base/.
- inlined trace_event.cc methods (4 total) so the trace_event_internal
  implementation is contained in headers.
- added new PPB_TraceEvent_Dev interface (implemented entirely on the plugin
  side)

BUG=93839
TEST=base_unittests, manual for plugin testing
