The property, if we decide to introduce, does not need to be too extensible. That is because within the section header type `Elf64_Shdr`, `sh_name, sh_offset, sh_size, sh_link, sh_info` can already be controlled. This patch makes sh_type/sh_entsize customiable. I wonder whether we want to support customized sh_flags.
