This patch replaces the handwritten MallocSizeOf implementation for PropertyDeclaration with a derived one, which gives much more thorough measurement. This requires (a) deriving MallocSizeOf for a *lot* of additional types (most of which already have `derive(HeapSizeOf)` in Servo builds), and (b) implementing MallocSizeOf for a few more types in the `malloc_size_of` crate. These changes would significantly improve the reporting coverage for gmail if it weren't for the fact that SpecifiedUrl isn't measured due to a lack of clarity about its fields; that can be fixed as a follow-up once bug 1397971 has landed.
