Remove hard code video resolution in C code and use PCD PcdVideoHorizontalResolution/PcdVideoVerticalResolution for customization. And when PcdConOutRow/PcdConOutColumn and PcdVideoHorizontalResolution/PcdVideoVerticalResolution are all set to 0, the console will be max video resolution and max text mode.
