tdf#148647: make sure to update own content on Win clipboard change HEADmaster

Before, only a new call to setContents, or destruction of the data
object referenced from CWinClipboard, would force CWinClipboard to
clean its m_pCurrentClipContent. A data object could be referenced
elsewhere, and so not get destroyed on clipboard change; this kept
the value of m_pCurrentClipContent, and all the following calls to
getContents would still return that stuck own data object.

This change makes CWinClipboard  store new own data object pointer
into temporary m_pNewOwnClipContent.  In onClipboardContentChanged
notification, the value is moved to m_pCurrentOwnClipContent. This
ensures that following onClipboardContentChanged events will clear
m_pCurrentOwnClipContent, preventing stuck clipboard content.
