Summary: We were treating the GUIDs in TypeServer2Record as strings, and the non-ASCII bytes in the GUID would not round-trip through YAML. We already had the PDB_UniqueId type portably represent a Windows GUID, but we need to hoist that up to the DebugInfo/CodeView library so that we can use it in the TypeServer2Record as well as in PDB parsing code.
