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.
