- Continue implementation of KiRosFrldrLpbToNtLpb by parsing the FreeLDR command line and:
  * Removing the ARC Boot path and splitting it into the ARC Boot Device Name, the ARC HAL Device Name, and the NT Boot and HAL Path Names, saved in their respective LoaderBlock pointers.
  * Converting every slash to a space. ("/DEBUGPORT" -> " DEBUGPORT")
  * Now we can fully parse and read NTLDR command lines.
- Update various code in the kernel to:
  * Use LoaderBlock->ArcDeviceNamePath & friends instead of the command line.
  * Stop depending on slashes, and instead use strstr for parameters.
