Laszlo Ersek 1366cd58cd MdeModulePkg/Core/Dxe: log memory base and length, after lib ctors again
CoreInitializeMemoryServices() logs "BaseAddress" and "Length" with
DEBUG() before DxeMain() calls ProcessLibraryConstructorList()
explicitly. (Library construction is not an automatic part of the DXE
Core entry point.)

So those DEBUG()s in CoreInitializeMemoryServices() are issued against
an un-constructed DebugLib, and also against a -- possibly underlying --
un-constructed SerialPortLib.

Some DebugLib instances can deal with this (see for example commit
91a5b13650, "OvmfPkg/PlatformDebugLibIoPort: fix port detection for
use in the DXE Core", 2018-08-06), while some others can't (see for
example the DebugLib instance
"MdePkg/Library/BaseDebugLibSerialPort/BaseDebugLibSerialPort.inf"
coupled with the SerialPortLib instance
"ArmVirtPkg/Library/FdtPL011SerialPortLib/FdtPL011SerialPortLib.inf").

Addressing this issue in a SerialPortLib instance that underlies
BaseDebugLibSerialPort seems wrong; either the DebugLib instance should
cope directly with being called un-constructed (see again commit
91a5b13650), or the DXE Core should log relevant information *at
least* after library instances have been constructed. This patch
implements the latter (only for the "BaseAddress" and "Length" values
calculated by CoreInitializeMemoryServices()).
