Add a second bool argument to H5F_vfd_swmr_writer_end_of_tick() that
tells whether the call may wait for the reader tick to catch up.
Add stub routines vfd_swmr_writer_may_increase_tick_to() and
vfd_swmr_reader_did_increase_tick_to() for tests---e.g.,
vfd_swmr_zoo_writer/_reader---to use to coordinate their tick numbers.
vfd_swmr_writer_may_increase_tick_to(new_tick, wait_for_reader) returns
true if the writer may increase its tick number to `new_tick` without
overrunning the reader.
A reader uses vfd_swmr_reader_did_increase_tick_to() to tell a writer
that its tick number has increased.
