promisor-remote: teach lazy-fetch in any repo
This is one step towards supporting partial clone submodules. Even after this patch, we will still lack partial clone submodules support, primarily because a lot of Git code that accesses submodule objects does so by adding their object stores as alternates, meaning that any lazy fetches that would occur in the submodule would be done based on the config of the superproject, not of the submodule. This also prevents testing of the functionality in this patch by user-facing commands. So for now, test this mechanism using a test helper. Besides that, there is some code that uses the wrapper functions like has_promisor_remote(). Those will need to be checked to see if they could support the non-wrapper functions instead (and thus support any repository, not just the_repository).
