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.

* 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.

The BaseTools/Scripts/ConvertMasmToNasm.py script was used to convert
X64/EbcLowLevel.asm to X64/EbcLowLevel.nasm
And, manually update nasm code to use mov rcx, dword value and generate
the same assembly code with rcx register to asm code.

even if the native function's arguments are less than 4.
From MSDN x64 Software Conventions, Overview of x64 Calling Conventions:
“The caller is responsible for allocating space for parameters to the
callee, and must always allocate sufficient space for the 4 register
parameters, even if the callee doesn’t have that many parameters.
This aids in the simplicity of supporting C unprototyped functions,
and vararg C/C++ functions.”
