Ard Biesheuvel 095fcfc606 MdeModulePkg/EbcDxe: implement the PE/COFF emulator protocol
Implement the new EDK2 PE/COFF image emulator protocol so that we can
remove the EBC specific handling in the DXE core and other places in
the core code.

Ard Biesheuvel 16dc5b68fc MdeModulePkg/EbcDxe: use EfiBootServicesCode memory for thunks
The EBC driver emits thunks for native to EBC calls, which are short
instructions sequences that bridge the gap between the native execution
environment and the EBC virtual machine.

Since these thunks are allocated using MemoryAllocationLib::AllocatePool(),
they are emitted into EfiBootServicesData regions, which does not reflect
the nature of these thunks accurately, and interferes with strict memory
protection policies that map data regions non-executable.

So instead, create a new helper EbcAllocatePoolForThunk() that invokes the
AllocatePool() boot service directly to allocate EfiBootServicesCode pool
memory explicitly, and wire up this helper for the various architecture
specific thunk generation routines.

Pete Batard 6f0a3cd23e MdeModulePkg/EbcDxe: prepare support for EBC Debugger
* This patch introduces EbcDebuggerHook.c/h and inserts the required
  EBCDebugger references into the existing EBC source files.
* With all the hooks defined to their empty version in EbcDebuggerHook.c
  the existing EBC VM behaviour is left unaffected.

jyao1 fa97cbf4ef 1) Fix GCC version EBC interpreter bug.
Add missing EFIPAI for EbcInterpret and ExecuteEbcImageEntryPoint().
	Get return value in EbcLLCALLEXNative(), remove EbcLLGetReturnValue().

2) Fix IA32 EBC interpreter bug on MOVsnw and MOVsnd.

3) Some cleanup
	Add missing ReturnEBCStack() for IA32 build.
	Remove unnecessary EbcLLGetStackPointer() for X64 and IPF build.
	Remove deadcode EbcLLGetStackPointer() and EbcLLGetReturnValue() in IA32/X64/IPF ASM code.
	Dump more info in CommonEbcExceptionHandler().

lgao4 c8ad2d7a29 Clean up the private GUID definition in module Level.
0. Remove the unused private GUID from module source files.
1. Use gEfiCallerIdGuid replace of the private module GUID.
2. Add the public header files to define HII FormSet and PackageList GUID used in every HII driver.
3. Move two EBC protocols for debug purpose from EBC driver to MdeModulePkg Include directory.
