MdePkg/BaseIoLibIntrinsic: Add EBC support

The EBC instruction set supports memory and MMIO access, but not
I/O port access.  Add EBC support to BaseIoLibIntrinsic that
generates an ASSERT() if the IoReadXX()/IoWriteXX() APIs are used.
This matches the implementation for other CPU types that do not
support I/O port access.
