These flags were split between cache.h and packfile.h,
because some of the flags apply only to packs. However, they
share a single numeric namespace, since both are respected
for the packed variant. Let's make sure they're defined
together so that nobody accidentally adds a new flag in one
location that duplicates the other.
While we're here, let's also put them in an enum (which
helps debugger visibility) and use "(1<<n)" rather than
counting powers of 2 manually.

Arguably, all of these for_each_*_object() functions should stay
together. Even though some are related to packfiles and some to loose,
they are meant to be a unified API. So I'd be fine to do that on top,
but this at least reduces the chance of a mistake in the meantime.
