This feature is the same as Stack Guard enabled in driver CpuDxe but applies to PEI phase. Due to the specialty in PEI module dispatching, this driver is changed to do the actual initialization in notify callback of event gEfiPeiMemoryDiscoveredPpiGuid. This can let the stack guard apply to as most PEI drivers as possible. To let Stack Guard work, some simple page table management code are introduced to setup Guard page at base of stack for each processor.
