[FREELDR] Diverse enhancements.

- Get rid of the FsCloseFile(), FsReadFile(), FsGetFileInformation(),
  FsGetFileSize() and FsSetFilePointer() wrappers and use the ARC
  functions directly instead. Make FsOpenFile() return an ARC file
  descriptor ID of the correct type. Get rid of unused FS_* defines.

- Use TRACEs in the ***Mount() filesystem functions for diagnostics
  purposes.

- Remove a leak in FatGetFatEntry(). Assign stuff via QuadPart where
  possible in FatMount(). Remove an unused member in FAT_FILE_INFO.

- Reduce code indentation in BtrFsMount() and remove a leak there.

- Disable reading the "BootPath" parameter in the linux loader since
  we don't use this parameter (yet??)
