[COFF] De-virtualize Chunk and SectionChunk Shaves another pointer off of SectionChunk, reducing the size from 96 to 88 bytes, down from 144 before I started working on this. Combined with D62356, this reduced peak memory usage when linking chrome_child.dll from 713MB to 675MB, or 5%. Create NonSectionChunk to provide virtual dispatch to the rest of the chunk types.
