packfile: move MIDX into packfile store

The multi-pack index still is tracked as a member of the object database
source, but ultimately the MIDX is always tied to one specific packfile
store.

Move the structure into `struct packfile_store` accordingly. This
ensures that the packfile store now keeps track of all data related to
packfiles.
