OvmfPkg/LoongArchVirt: Add the early serial port output library Add a early serial port output library into LoongArchVirt that named EarlyFdtSerialPortLib16550, this library is referenced from MdeModulePkg. This library is used in the PEI phase. Since the serial port address can not be saved in memory of the LoongArch QEMU virtual machine in the PEI phase, the serial prot base address will be obtained from the FDT before each output.
