Restore two more Qt5-only code paths on Qt6 (parts list, print dialog)

Browse Source 
Two further empty Qt6 guard branches found by ispyisail in
qelectrotech#553:

- Element editor parts list: the QGraphicsItem* was only stored into
  the list item on Qt5, so on Qt6 selecting a part in the list silently
  stopped selecting it on the canvas. QVariant::fromValue() works on
  both (Qt itself declares the metatype), guard removed.

- Print dialog: setEnabledOptions() is a Qt4-era API removed in Qt6;
  setOptions() is the modern spelling with the same replace-the-set
  semantics and exists on both, guard removed.

Both builds (Qt 5.15.2 and Qt 6.11.1) compile clean.

(cherry picked from commit 759d1c078e23664482850bad2e91d668b93aadcf)
