Current FSP utilizes pre-allocated temporary memory from
boot loader for both heap and stack. To reduce overall
temporary memory usage FSP may share the same stack with
boot loader and only needs a smaller memory for heap,
no separate memory required for stack.
Setting PcdFspHeapSizePercentage to 0 to enable FSP sharing
stack with boot loader, in this case boot loader stack
has to be large enough for FSP to use. Default is 50
(half memory heap and half memory stack) for backward
compatible with original model.
Test: Verified on internal platform and booting successfully
with both modes.

Add FSP2.0 support.
This series of patch is to support FSP2.0 specification at
https://firmware.intel.com/sites/default/files/FSP_EAS_v2.0_Draft%20External.pdf
Some major updates include:
1) One FSP binary is separated to multiple components:
FSP-T, FSP-M, FSP-S, and optional FSP-O.
Each component has its own configuration data region.
2) All FSP-APIs use same UPD format - FSP_UPD_HEADER.
3) Add EnumInitPhaseEndOfFirmware notifyphase.
4) FSP1.1/FSP1.0 compatibility is NOT maintained.
5) We also add rename Fsp* to FspWrapper* in IntelFsp2WrapperPkg,
to indicate that it is for FspWrapper only.
IntelFspPkg and IntelFspWrapperPkg will be deprecated.
The new Intel platform will follow FSP2.0 and use IntelFsp2Pkg
and IntelFsp2WrapperPkg.
The old platform can still use IntelFspPkg and IntelFspWrapperPkg
for compatibility consideration.
