Summary: The code for serializing minidumps was living in MinidumpYAML.cpp so that it would be accessible from unit tests. While this had its advantages, it was also unfortunate because it broke symmetry with all other yaml2obj serializers. Fortunately, nowadays all of yaml2obj is a library, so we don't need to do anything special. This patch improves the code consistency by moving the serialization code to MinidumpEmitter.cpp to match the style used in other backends. It also removes the writeAsBinary entry point in favor of the more general convertYAML interface. This patch is just massaging the code a bit. There shouldn't be any functional change here.
