target: Add target_core_backend_configfs.h helper macros

This patch adds a number of configfs e-attr macros following
what existing target_core_configfs.c code does for internal
target_backend_dev_attrib setup, and similar to how target

a default list of attributes for other backend drivers like
IBLOCK, FILEIO, RAMDISK, and TCMU.
