Add generic SerialPortLib instance for 16550 UARTs configured through PCDs. Depends on new library class called PlatformHookLib to perform platform specific initialization of the UART.
Add PlatformHookLib.h that defines the PlatformHookLib class
Add PlatformHookLibNull instance that is a Null implementation of the PlatformHookLib class
