Move from deprecated type/symbols/structures to valid ones

[donho]

They are some deprecated type/symbols/structures in the current version of Notepad++ (v8.4.7). And these type/symbols/structures will be deprecated in the future release of Scintilla.

The deprecated type / symbols / structures in Scintilla
Sci_PositionCR, SCI_FINDTEXT, SCI_FORMATRANGE, SCI_GETTEXTRANGE, Sci_CharacterRange, Sci_TextRange, Sci_TextToFind and Sci_RangeToFormat
should be replaced respectively by
Sci_Position, SCI_FINDTEXTFULL, SCI_FORMATRANGEFULL, SCI_GETTEXTRANGEFULL, Sci_CharacterRangeFull, Sci_TextRangeFull, Sci_TextToFindFull and Sci_RangeToFormatFull in your plugins ASAP.

Please update the header files (essentially Sci_Position.h and Scintilla.h, but updating menuCmdID.h, Notepad_plus_msgs.h and PluginInterface.h is also recommaned) from here:
