Update MdePkg BaseRngLib and SecurityPkg RngDxe to add support for
the AARCH64 RNDR instruction.
Changes from v1 to v2:
o Added a PCD, gEfiSecurityPkgTokenSpaceGuid.PcdCpuRngSupportedAlgorithm to
specify which algorighm the platform supports.
o Moved ArmRndr() and ArmRndrrs() into BaseRngLib.
o Added Doxygen headers.
o Merged X64 and AARCH64 *GetBytes functions into a single RngGetBytes
function.
o Updated constructors to return EFI_STATUS instead of RETURN_STATUS.
o Added ArchIsRngSupported function that gets called before each call to
ArchGetRandomNumber*.
