[FIX] core.IconPool: add local font path for SAP-icons Icon Font

- Internet Explorer provide the user the possibility to block the download of
  font file. In such a case, the UI5 icon font doesn't work anymore. The
  possible solution would be to install the font file locally and we also try to
  load the font file from local font folder.
