[REGEDIT] Fix ListView selection and finding (#5150)

Browse source 
We will check the data size correctly, instead of 3 NUL byte appending hack. Add bSelectNone parameter to UpdateAddress and RefreshListView functions. If bSelectNone is TRUE, then select nothing of ListView. Fix item selection of ListView. Rename CompareData helper function as MatchData and improve it. Improve the search algorithm. If the item selection of ListView changed, scroll down to the item. Follow up to #5146. CORE-15986, CORE-18230
