Oliver Smith-Denny 58766a4729 FatPkg: Validate Reserved FAT Entries on Volume Open 
There are two reserved FAT entries in the FAT filesystem that
are expected to have valid contents in them. Today the FAT drivers
do not validate these entries when reading from a device for the
first time. This can cause infinite loops in the FAT driver when
trying to read corrupted disks as reported in
https://github.com/tianocore/edk2/issues/9679.

This PR follows the recommended update requested in that bug to
check the two reserved FAT entries and validate their contents
against the spec defined values in both FatPei and EnhancedFatDxe
when opening a device for the first time.

Hao Wu 4c5ee6a694 FatPkg: Explicitly declare FAT_CLUSTER_SPECIAL as unsigned type 
In FatPkg, cluster-related varibles are declared as unsigned type (e.g.
UINT32/UINTN). To keep the comparisions involving those variables
type-matched, declare the definition FAT_CLUSTER_SPECIAL as unsigned type
explicitly.
