[SETUPLIB] Consolidate the FsUtil and PartList modules of the SetupLib.
- Add a PreparePartitionForFormatting routine that sets the partition ID depending on
the chosen filesystem.
- The 'FORMATMACHINESTATE FormatState' machine-state and the
'TempPartition' members of the partition list structure is purely a USETUP
convenience, so remove them from the PARTLIST structure and move them back into USETUP.
- Attempt to recognize the filesystem (set the 'FileSystem' member of
PARTENTRY) of partitions we are adding into the PARTLIST list.
- Fix the return value of the SelectPartition function, which is by the way completely
broken (it doesn't do what it is supposed to do; alternatively its naming is
completely wrong...).
