Add REQUIRES_OTHER_BODY_SPECIFIC_ASSETS glitch

This helps with items like "Living in Watermelon Foreground and Background", which has a species-specific foreground and bodyId=0 background.

With this flag set on the background, it won't appear for pets that don't _also_ have something else that fits. In this case, it hides it from Standard Vandas, and all non-standard colors.

There's some hacky limitations here: the item page still highlights the Vanda, even though clicking gives nothing; and the zone info for it is messy too, with the Background claiming to fit all species, and the LFI claiming to fit 54 specific species. But those don't seem important enough to code for!
