Git allows setting a different object directory via
'GIT_OBJECT_DIRECTORY', but provides no equivalent for references.
This asymmetry makes it difficult to test different reference backends
or use alternative reference storage locations without modifying the
repository structure.
Add a new environment variable 'GIT_REF_URI' that specifies both the
reference backend and directory path using a URI format:
<ref_backend>://<URI-for-resource>
When set, this variable is used to obtain the main reference store for
all Git commands. The variable is checked in `get_main_ref_store()`
when lazily assigning `repo->refs_private`. We cannot initialize this
earlier in `repo_set_gitdir()` because the repository's hash algorithm
isn't known at that point, and the reftable backend requires this
information during initialization.
When used with worktrees, the specified directory is treated as the
reference directory for all worktree operations.
Add a new test file 't1423-ref-backend.sh' to test this environment
variable.
