MdePkg: introduce DxeRuntimeDebugLibSerialPort Introduce a variant of BaseDebugLibSerialPort that behaves correctly with regards to the use of the serial port after ExitBootServices(). At boot time, all DEBUG() prints and ASSERT() invocations are executed normally. At runtime, DEBUG() prints are dropped entirely, and ASSERT()s omit the serial output as well, and only perform the configured post-ASSERT() action, i.e., issue a CPU breakpoint or enter a deadloop.
