Doc: add detail about EXPLAIN's "Disabled" property
c01743aa4 and later 161320b4b adjusted the EXPLAIN output to show which
plan nodes were chosen despite being disabled by the various enable*
GUCs. Prior to e22253467, the disabledness of a node was only evident by
a large startup cost penalty. Since we now explicitly tag disabled nodes
with a boolean property in EXPLAIN, let's add some documentation to
provide some details about why and when disabled nodes can appear in the
plan.
