Remove pg_control's enableIntTimes field. 

We don't need it any more.

pg_controldata continues to report that date/time type storage is
"64-bit integers", but that's now a hard-wired behavior not something
it sees in the data.  This avoids breaking pg_upgrade, and perhaps other
utilities that inspect pg_control this way.  Ditto for pg_resetwal.

I chose to remove the "bigint_timestamps" output column of
pg_control_init(), though, as that function hasn't been around long
and probably doesn't have ossified users.
