profiling: Adds initial UProf accounting to Cogl

This adds gives Cogl a dedicated UProf context which will be linked together
with Clutter's context during clutter_init_real().

Initial timers cover _cogl_journal_flush and _cogl_journal_log_quad

You can explicitly ask for a report of Cogl statistics by exporting
COGL_PROFILE_OUTPUT_REPORT=1 but since the context is linked with Clutter's
the statisitcs will also be shown in the automatic Clutter reports.
