This allows us to use yaml2obj and obj2yaml to round-trip CodeView symbol and type information without having to manually specify the bytes of the section. This makes for much easier to maintain tests. See the tests under lld/COFF in this patch for example. Before they just said SectionData: <blob> whereas now we can use meaningful record descriptions. Note that it still supports the SectionData yaml field, which could be useful for initializing a section to invalid bytes for testing, for example.
