[PATCH] [RFC][GSoC 2026] builtin/repo: avoid global state in get_layout_bare

The get_layout_bare() function accepts a struct repository *repo
argument but marks it UNUSED and instead relies on
is_bare_repository(), which depends on global state.

As bareness is a per-repository property, this causes the function
to always report the status of the global repository, even when a
specific repository instance is provided.

This change computes the bare status using the passed-in repository
instance (based on core.bare and the absence of a worktree),
thereby removing the dependency on global state.

This patch is sent as an RFC to solicit feedback on whether using
repository-local state here is the preferred approach.
