trace2:data: add trace2 regions to wt-status

Add trace2_region_enter() and trace2_region_leave() calls around the various phases of a status scan. This gives elapsed time for each phase in the GIT_TR2_PERF and GIT_TR2_EVENT trace target. Also, these Trace2 calls now use s->repo rather than the_repository. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
