[RFC GSoC PATCH v3 2/2] attr: use local repository state in read_attr

[Ayush Jha <kumarayushjha123@gmail.com>]

The read_attr function currently relies on is_bare_repository() to decide whether to check the index or working tree for attributes. This function implicitly depends on the_repository, which is incorrect for library code handling secondary repositories.

Update read_attr to use the new  repo_settings_get_is_bare(istate->repo)
helper. This ensures the logic respects the context of the specific repository associated with the index, while also benefiting from the lazy-loading optimization added in the previous commit.
