jljusten 02328a57a2 EMU Variable: Add support for pre-reserved NV variable store. 
Add PcdEmuVariableNvStoreReserved which allows a platform to declare a
memory address for the EMU Variable driver to use for the NV variable
store.  The EMU Variable driver will look to see if the contents of
this memory range appear to be a valid variable store, and if so
the EMU driver will use the variables.

If a platform can preserve a memory range across system resets, this
feature can allow the EMU Variable driver's NV variable store to be
preserved across a system reset.

In the default case this PCD will be set as a fixed PCD with a value
of 0.  In this case this new feature should have minimal impact on
the EMU Variable driver.  (Perhaps a slight increase in code size,
but no functional difference is expected.)

eric_tian 841014ba97 refine VariablePei driver to unify the algorithm of access VariableIndexTable among various archs. 
1. record the distance of two neighboring VAR_ADDED type variables rather than the offset of each variable. As the field recording this info is UINT16 width, the latter causes in IA32/X64 platform, it can only cache those variables from offset 0 to offset 2^16; in IPF platform, from offset 0 to offset 2^18(extend the scope by left-shift the offset two bits).
when taking the former algorithm, the max range of caching variable is from offset 0 to offset 122*(2^16)
