ShellPkg: Fix smbiosview system enclosure type table

The SystemEnclosureTypeTable in QueryTable.c contained a couple
of errors: value 0x10 is "Lunch Box" not "Main Server Chassis", and
the Sub Notebook value was repeated as 0x13 when that entry is for
"SubChassis". The entries in-between needed adjusted.
