sd lok: add LOK_CALLBACK_PARTS_COUNT_CHANGED callback

In the tiled rendering case, when a slide is deleted or inserted
the sorted slides are updated on client side.

However, when .uno:Undo and .uno:Redo actions are requested on
client side the sorted slides are required to update all
sorted slides.

So every time when .uno:InsertPage, .uno:DeletePage, .uno:Undo, .uno:Redo
actions are requested, it will notify verbose action (PageInserted, PageDeleted)
with index on client side to update the sorted slide index.
