ArmVirtPkg: steer DebugLib output away from SerialPortLib+console traffic
For the RELEASE target, all ArmVirtPkg DSCs inherit BaseDebugLibNull from
"ArmVirt.dsc.inc"; keep that.
For NOOPT and DEBUG:
- switch the lib class resolution pair (BaseDebugLibSerialPort +
FdtPL011SerialPortLib) that is set as the default for all module types
in "ArmVirt.dsc.inc" to DebugLibFdtPL011UartRam;
- switch the lib class resolution pair (BaseDebugLibSerialPort +
EarlyFdtPL011SerialPortLib) that is set as an override for SEC,
PEI_CORE, PEIM modules in "ArmVirt.dsc.inc" to
DebugLibFdtPL011UartFlash;
- switch the lib class resolution pair (DxeRuntimeDebugLibSerialPort +
FdtPL011SerialPortLib) that is set as an override for DXE_RUNTIME_DRIVER
modules in "ArmVirt.dsc.inc" to DxeRuntimeDebugLibFdtPL011Uart;
- mask all of the above DebugLib class resolution changes in
"ArmVirtKvmTool.dsc", because "ArmVirtKvmTool.dsc" uses
BaseSerialPortLib16550 rather than PL011 UARTs,
- mask all of the above DebugLib class resolution changes in
"ArmVirtXen.dsc" too, because "ArmVirtXen.dsc" uses
XenConsoleSerialPortLib rather than PL011 UARTs.
I regression-tested this change for "ArmVirtKvmTool.dsc" and
"ArmVirtXen.dsc" by building them for both DEBUG and RELEASE, both before
the patch and after, and comparing the edk2 build report files (focusing
on lib class resolutions). There are no changes.
