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.
