tdf#158317 fix cleanup of SfxPoolItems in editeng

It is not possible to use implCreateItemEntry/implCleanupItemEntry,
that is tooling limited *by purpose* to svl/Item/ItemSet stuff.
But what I can do is to do that SfxPoolItemHolder I already
talked/thought about. It is a helper that can safely hold a
SfxPoolItem in cases where an SfxItemSet is too expensive.
Think about it as a SfxItemSet for a single item. That solves
the problem why DirectPutItemInPool/DirectRemoveItemFromPool
is used in general (each usage is a 'compromize').
Did that now, works well. Editengine is now free of
DirectPutItemInPool/DirectRemoveItemFromPool.

Replaced ::CursorMoved with checkAndDeleteEmptyAttribs since all
these got static with no longer need to DirectRemoveItemFromPool.
Corrected create/delete counters.
