Minor additional refactoring of planner.c's PathTarget handling. Teach make_group_input_target() and make_window_input_target() to work entirely with the PathTarget representation of tlists, rather than constructing a tlist and immediately deconstructing it into PathTarget format. In itself this only saves a few palloc's; the bigger picture is that it opens the door for sharing cost_qual_eval work across all of planner.c's constructions of PathTargets. I'll come back to that later.
In support of this, flesh out tlist.c's infrastructure for PathTargets a bit more.
