ArmPlatformPkg/ArmVirtualizationPkg: add ArmVirtualizationPlatformLib library This is an implementation of ArmPlatformLib that discovers the size of system DRAM from a device tree blob located at the address passed in gArmTokenSpaceGuid.PcdDeviceTreeBaseAddress, which should equal the value in gArmTokenSpaceGuid.PcdSystemMemoryBase. As the device tree blob is passed in system DRAM, this library can only be used if sufficient DRAM is available (>= 128 MB) and if not using shadowed NOR. The reason for this is that it makes it easier to guarantee that such a device tree blob at base of DRAM will not be clobbered before we get a chance to preserve it.

ArmVirtualizationPkg: use a HOB to store device tree blob Instead of using a dynamic PCD, store the device tree address in a HOB so that we can also run under a configuration that does not support dynamic PCDs. This also adds MemoryAllocationLib to the [LibraryClasses] section of ArmVirtualizationPlatformLib/ArmVirtualizationPlatformLib.inf, as this dependency was formerly satisfied transitively through one of the library dependencies that were dropped.

ArmVirtPkg/ArmVirtPlatformLib: reduce ID map size to GCD region size The ID mapping routines on virtual platforms simply map the entire hardware supported physical address space as device memory, and then punch some holes for regions that need to be mapped cacheable. On virtual platforms hosted on CPUs that support a large physical address range, this may result in a lot of overhead, i.e., 4 KB of page tables for each 512 GB of address space, which quickly adds up (i.e., 2 MB for the architectural maximum of 48 bits). Since there may be a platform specific limit to the size of the (I)PA space that is not reflected by CPU id registers, restrict the range of the ID mapping to gEmbeddedTokenSpaceGuid.PcdPrePiCpuMemorySize bits. This makes sense by itself, since we cannot manipulate mappings above that limit anwyay (because they are not covered by GCD), and it allows the PCD be set to a lower value by platforms whose (I)PA space is smaller than the hardware supported maximum.
