Subject: GHS: Update setting default OS location for Integrity platforms

-- Update how the latest OS is determined; scan the location GHS_OS_ROOT and sort it
   No longer use registry settings looking for installations
     The registry values are assigned in installation order for Green Hills tools not version order
   Filter out files from the list of directories (i.e if int1234.zip and int1234 are both in root folder)
