Rename field "relkind" to "objtype" for CTAS and ALTER TABLE nodes

Browse Source 
"relkind" normally refers to the char field from pg_class.  However, in
the parse nodes AlterTableStmt and CreateTableAsStmt, "relkind" was used
for a field of type enum ObjectType, that could refer to other object
types than those possible for a relkind.  Such fields being usually
named "objtype", switch the name in both structures to make things more
consistent.  Note that this led to some confusion in functions that
also operate on a RangeTableEntry object, which also has a field named
"relkind".

This naming goes back to commit 09d4e96, where only OBJECT_TABLE and
OBJECT_INDEX were used.  This got extended later to use as well
OBJECT_TYPE with e440e12, not really a relation kind.
