Size of the FTW spare block range. Note that this value should larger than PcdFlashNvStorageVariableSize and block size aligned.
The root cause is that variable driver will use FTW protocol to reclaim variable region.
If the length of variable region is larger than FTW spare size, it means the whole variable region can not
be reflushed through the manner of fault tolerant write.
