refs: break out ref conflict checksdt/refs-backend-pre-vtable
Create new function find_descendant_ref, to hold one of the ref conflict checks used in verify_refname_available. Multiple backends will need this function, so move it to the common code. Also move rename_ref_available to the common code, because alternate backends might need it and it has no files-backend-specific code.
