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.

FSP should not override IDT table when it is initialized
by boot loader. IDT should be re-initialized in FSP only
when it is invalid.
To mitigate temporary memory usage a PCD
PcdFspMaxInterruptSupported created for platform to decide
how many interrupts the FSP IDT table can support.
Test: Verified on internal platform and boots successfully.

Add support for both API (original mode) and DISPATCH mode:
1. Add FspMode field from reserved byte of Global
Data Structure to tell which mode is selected by boot
loader. If boot loader invoking FSP-M API this field
will remain as default 0 (API mode), otherwise platform
FSP should set this field to 1 (Dispatch mode) when
initializing Global Data Structure.
2. gFspInApiModePpiGuid will be instaled when FSP running in API
mode and modules only for API mode should have this in depex.
3. If it is DISPATCH mode, FSP will return to PEI dispatcher,
not directly return to boot loader.
4. DISPATCH mode supports DXE NotifyPhase drivers so FSP
will not wait for PEI NotifyPhase callbacks, instead it
will install gFspReadyForNotifyPhasePpiGuid PPI for
platform to complete late initialization before transferring
to DXE.
Test: Verified FSP API and DISPATCH modes on 2 internal
platforms and both boot successfully.

Commit formats had issues so reverted 9 commits
from IntelFsp2Pkg and IntelFsp2WrapperPkg.
Will re-submit them with correct formats.

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.
