LCL: fix some inconsistencies in translating dialog titles (patch from cobines, bug #19869):

a) TSavePictureDialog
      - override DefaultTitle
      - do not set Title in Create (already done in inherited constructor)
      - set fCompStyle:=csSaveFileDialog (as in TSaveDialog)

    b) TCalculatorDialog
      - don't use your own Title, but use inherited Title property
      - override DefaultTitle

    c) TCalendarDialog
      - don't use your own DialogTitle, but use inherited Title property
      - remove DialogTitle property
      - override DefaultTitle
