payloads/external/tianocore: Hook up debug builds to serial support 

ConSplitterDxe uses the intersection of all outputs, which includes
serial, for the list of supported text modes. When serial output is
supported, this slows down performance and limits the size of
FrontPage.

Only enable edk2's serial support when it's a debug build as
it's the only case where there will be debug output.
