[PATCH] D34127: Make obj2yaml and yaml2obj support .debug$S and .debug$T sections

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.
