Improve and modernize logging for Process::CompleteAttach() (llvm#82717)

Target::SetArchitecture() does not necessarily set the triple that is
being passed in, and will unconditionally log the real architecture to
the log channel. By flipping the order between the log outputs, the
resulting combined log makes a lot more sense to read.
