The function ArmPlatformInitializeSystemMemory() is defined by
ArmPlatformLib, but is only ever called when using the PrePeiCore
flavor of the startup code. Also, none of the remaining upstream
platforms actually implement anything in that function in the first
place. So let's just remove it altogether.

Problems have been encountered because some of the source files have
execute permission set. This can cause git to report them as changed
when they are checked out onto a file system with inherited permissions.
This has been seen using Cygwin, MinGW and PowerShell Git.
This patch makes no change to source file content, and only aims to
correct the file modes/permissions.

MemoryInitPeim short-circuits its MemoryInitPeiLib dependency by including
the .c file directly. This prevents us from having a special implementation
for ArmVirtualizationPkg that performs additional cache maintenance before
enabling the MMU. So instead, make it depend on the library class.

This changes the definition and a bunch of references to
gArmTokenSpaceGuid.PcdSystemMemoryBase and
gArmTokenSpaceGuid.PcdSystemMemorySize so they can be declared as dynamic PCDs
by the platform. Also, move the non-SEC call to
ArmPlatformInitializeSystemMemory() earlier, so a platform has a chance to set
these PCDs before they are first referenced.
The purpose is allowing dynamically instantiated virtual machines to declare
the system memory by passing a device tree.

The denomination 'Normal' was used to make reference to the 'Normal'
or 'Non Secure' or 'Non Trusted' world.
To avoid confusion, this prefix has been removed from PCDs to define
the normal world.
The PCDs explicitely related to the Secure/Trusted World continue to
have the 'Sec' prefix.

In the former memory model, the UEFI firmware was expected to be located
at the top of the system memory. Stacks & Pi memory regions were set below
the firmware.
On some platform, the UEFI firmware could be shadowed by the ROM firmware
(case of the BeagleBoard) and in some cases the firmware is copied at the
beginning of the system memory.
With this new memory model, stack and Pi/DXE memory regions are set at the
top of the system memory wherever the UEFI firmware is located in the memory
map.
Because DXE core does not support shadowed firmwares, the system memory covered
by the UEFI firmware is marked as 'Non Present' to avoid to be overlapped by
DXE allocations.

Feature PCDs cannot be used in assembly files.
The PcdStandalone PCD is needed in one of the assembly file of the

In the aim to reuse the memory init features in a PrePi module (use to
skip the PEI Core), this module has been divided into two files:
- MemoryInitPeiLib: declare the memory HOBs
- MemoryIniPeim: PEIM warpper for the library
