The "cache-tree" subsystem still depends on `the_repository`. Adapt it to instead use repositories provided via the context, either as a new parameter or the one passed in via `struct index_state`. Besides getting rid of `the_repository`, this also removes the last dependency on registering submodule sources with the main object database. When reading gitmodules from a submodule's index we implicitly read that object via `the_repository`'s object database, which is of course wrong. This works though because we would then register the submodule's object database with the main object database, but a later patch is going to get rid of that mechanism. You can verify that we indeed no longer depend on this mechanism by running tests with `GIT_TEST_FATAL_REGISTER_SUBMODULE_ODB=true`. Without this patch we fail in t1092, with this patch we never register submodule object databases anymore.
