[Outreachy PATCH v3 1/2] remote: add repo_for_each_remote()

[Okhuomon Ajayi <okhuomonajayi54@gmail.com>]

for_each_remote() always reads the remotes of the_repository.

Add repo_for_each_remote(), which takes a repository, and turn
for_each_remote() into a wrapper that passes the_repository.
Callers that are given a repository, such as
unique_tracking_name() in the next patch, can then use the
remotes of that repository.
