trace2: add trace2 tracing of major regions in 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. Signed-off-by: Jeff Hostetler <[email protected]>
