objdump: Support newer ObjC image info flags
Summary:
Add support for two additional ObjC image info flags: `IS_SIMULATED` and
`HAS_CATEGORY_CLASS_PROPERTIES`.
`IS_SIMULATED` indicates a Mach-O binary built for iOS simulator.
`HAS_CATEGORY_CLASS_PROPERTIES` indicates a Mach-O binary built by a compiler
that supports class properties in categories.
