OvmfPkg: Add NV Variable storage within FD
This is to prepare for QEMU flash support which will allow
non-volatile variables to be saved in the flash image.
Note two size changes:
* NV Varstore size increased from 0xc000 to 0xe000
* FTW work size decreased from 0x2000 to 0x1000
The reason for this change is that the fault-tolerant write
support requires that the work area fit within the block
just before the fault-tolerant write spare storage blocks.
Since QEMU flash blocks have a size of 0x1000, this means
that the maximum FTW work size is 0x1000.
v2:
* Update commit message and PcdVariableStoreSize
