MdePkg: Expand BaseIoLibIntrinsic (IoLib class) library The UefiCpuPkg/CpuIo2Dxe driver and the QemuCfgLib library have duplicate implementations of I/O Fifo routines. This patch clones the I/O Fifo routines into the BaseIoLibIntrinsic library and expands the IoLib class to include the ported I/O Fifo routines.
