CorebootPayloadPkg: Consume PlatformHookLib in PlatformBootManagerLib

When coreboot uses different baud rate from the default (115200), the
current BDS driver will not be able to enable serial console display
due to the inconsistent serial port PCD settings.  By adding the
PlatformHookLib reference in the inf file, it will enforce the PCDs
to be aligned with what have been passed from coreboot.
