[Outreachy PATCH] list-objects-filter-options: pass repository to partial clone helpers

[Dorine Tipo <dorine.a.tipo@gmail.com>]

partial_clone_register() and partial_clone_get_default_filter_spec()
use `the_repository` to look up promisor remotes and to update the
repository's configuration, which ties them to the main repository of
the process.

Accept the repository as a parameter instead, and have the callers in
builtin/clone.c and builtin/fetch.c pass `the_repository` explicitly.
This moves the dependency on the global one level up, without changing
behavior.

The file no longer uses `the_repository` after this change. I left
USE_THE_REPOSITORY_VARIABLE in place to keep this patch focused, and
can drop it here or in a follow-up, whichever is preferred.
