status: cleanup API to wt_status_print

Refactor the API between builtin/commit.c and wt-status.[ch].

Hide the details of the various wt_*status_print() routines inside
wt-status.c behind a single (new) wt_status_print() routine.
Eliminate the switch statements from builtin/commit.c.
Allow details of new status formats to be isolated within wt-status.c
