This change is triggered by R18654 "Enhance variable performance by reading from existed memory cache"
that changed the code to use CacheVariable to improve performance.
So the CacheVariable->InDeletedTransitionPtr NULL pointer check needs to be moved to the place before
it is been used.

Current variable driver already have memory cache to improve performance.
Change the code which read from physical MMIO address to read from memory cache.

between variable HOB and NV storage.
Variable HOB may be built by a system that supports and loads variable
default, the variables in the HOB will be flush to NV storage after
variable write search ready.
After that, if the variable's Attributes is changed by someone and
system reboots and tries to load default again, the variable Attributes
mismatch case between variable HOB and NV storage will appear.
Original code did not handle the case correctly, that may eventually
cause NV storage contains two valid same variables that will lead to
system hang if GetNextVariableName() called.

What to do:
1. Merge from Auth Variable driver in SecurityPkg to Variable drive in
MdeModulePkg. Then the merged Variable driver in MdeModulePkg will
link to AuthVariableLib and TpmMeasurementLib.
AuthVariableLibNull and TpmMeasurementLibNull in MdeModulePkg
could be used for non auth variable support.
AuthVariableLib and DxeTpmMeasurementLib in SecurityPkg
may be used for auth variable support.
Why to do:
1. Remove code duplication and reduce maintenance effort.
After auth variable service separated from Auth Variable driver in SecurityPkg
to AuthVariableLib. The remaining code logic of Auth Variable driver in SecurityPkg
will be almost same with Variable driver in MdeModulePkg. Now it is to
merge them.

PEI variable implementation checks only the variable header signature for validity. This does not seem robust if system crash occurred during previous Reclaim() operation. If the crash occurred while FTW was rewriting the variable FV, the signature could be valid even though the rest of the FV isn't valid.
Solution: Add a FaultTolerantWritePei driver to check and provide the FTW last write status, then PEI variable and early phase(before FTW protocol ready) of DXE variable can check the status and determine if all or partial variable data has been backed up in spare block, and then use the backed up data.

The Variable PEI and RuntimeDxe drivers were using the attribute 'HeaderLength' of
EFI_FIRMWARE_VOLUME_HEADER without checking if a Firmware Volume Header was existing at
the base address.
In case the Firmware Volume Header does not exist or is corrupted, the attribute 'HeaderLength'
is a non valid value that can lead to a non valid physical address when accessing produces an
access error.
