Adjust trace_sort log messages.

Browse Source 
The project message style guide dictates: "When citing the name of an
object, state what kind of object it is".  The parallel CREATE INDEX
patch added a worker number to most of the trace_sort messages within
tuplesort.c without specifying the object type.  Bring these messages
into compliance with the style guide.

We're still treating a leader or serial Tuplesortstate as having worker
number -1.  trace_sort is a developer option, and these two cases are
highly comparable, so this seems appropriate.

Per complaint from Tom Lane.

Backpatch: 11-, where parallel CREATE INDEX was introduced.
