Pasted sheets do not have assigned SCH_SCREEN objects until after they
are loaded.
Do not recalculate connectivity unless the SCH_COMMIT object actually has
connectable schematic object changes.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/16579
Also fixes a memory leak in Symbol Editor undo/redo.
Also moves a few more things to SCH_COMMIT.
Also fixes a couple of LIB_ITEM::Clone() methods that were
failing to return the same uuid.
If a item is selected, its SELECTED, STARTPOINT and ENDPOINT flags cannot be cleared,
and must be still selected after changes to allow more move, rotate... commands.
Fix to previous commit 741c6f2d
The symbol editor has few enough items that it will still be performant
if we always send a selected-item-modifed event. (As it turns out we
were doing that anyway as the check for child-modified flags didn't
also check for selected.)
Also fixes a bug where Convert Symbol wasn't undoable.
Also cleans up some SetModified() call no longer needed with SCH_COMMIT.
Also fixes bug where revert of a modification didn't update the screen's
RTree.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/15030
While a SCH_SHEET does indeed have a SCH_SHEET parent, it's not one of
the children that gets added as a CHT_MODIFY of its parent.
Also fixes a bug where the newly drawn sheet gets removed from the
preview before running the dialog.

The connection graph should only be updated within the commit structure
because this is the only time the connectivity should be changed. We
want any connectivity changes to be included in the commit as well, so
this should be stored prior to the undo/redo list mods
