DEBUG builds of PEI code will print a diagnostic message regarding
the utilization of temporary RAM before switching to permanent RAM.
For example,
Total temporary memory: 16352 bytes.
temporary memory stack ever used: 4820 bytes.
temporary memory heap used for HobList: 4720 bytes.
Tracking stack utilization like this requires the stack to be seeded
with a known magic value, and this needs to occur before entering C
code, given that it uses the stack. Currently, only Nt32Pkg appears
to implement this feature, but it is useful nonetheless, so let's
wire it up for PrePeiCore.

The RVCT .asm files include AsmMacroIoLib.h only for the definition of
LoadConstantToReg (), which makes it tedious to make change to that file
without the risk of making the RVCT assembler unhappy. So simply replace
LoadConstantToReg() with mov32, which does the right thing in all cases.

This retypes some stack base PCD as 64-bit, and fixes up a number of references
to 64-bit PCDs (including the retypes ones), to use the correct PcdGet64()
accessors. Note that, in the case of FixedPcdGet64, this does not actually
caused any problems, since that resolves to an immediate value. But the
generic PcdGetxx accessors should be typed according to the size of the PCD.

Now that we dropped all ArmPlatformGlobalVariableLib dependencies,
there is no longer a need to allocate and clear out the global
variable region in the PrePeiCore init code. So remove it.

This function allows platform to do any specific actions prior to
the start the PEI phase.
For instance, this function could be used by some platforms to initialize clocks that
are required at the early stage of the PEI phase.

Checking if a core if the primary/boot core used to be done with the macro
IS_PRIMARY_CORE().
Some platforms exposes configuration registers to change the primary core.
Replacing the macro IS_PRIMARY_CORE() by ArmPlatformIsPrimaryCore() allows
some flexibility in the way to check the primary core.
