FolderView: Performance improvements for selections
This MR has multiple changes, especially related to the "rubberband" (selection
rectangle).
- Use `Qt.callLater` for `gridView.rectangleSelect` to eliminate redundant
calls.
- This was previously called *every time mouse moved one pixel*
- Clear a redundant mapToItem
- `var cPos = mapToItem(gridView.contentItem, mouse.x, mouse.y);` needs to be
only called during rubberband action
- Update dragItem images after selection is done, instead of every time a
delegate is selected
- Instead of creating and destroying `selectionButton` in `FolderItemDelegate`,
create it once and toggle its visibility
These all should help with the performance related to selecting multiple icons
by dragging the selectiong rectangle around them.
