Fix windows blank spaces in path not correctly handled

Open Thibaut ROMAIN requested to merge fix-windows-blankspace-paths into release-8.1

When unzipping OTB for windows in a path containing spaces, some apps does not work because of PROJ DB not correctly set, and GDAL_DATA too. It is due to the fact spaces are handled on windows, we have to adapt the .bat scripts that launch OTB apps on windows
