This patch enables yaml2obj to emit the .debug_aranges section in ELFYAML.

Besides, this patch helps correct the width of the variable `debug_info_offset` (4-byte in 32-bit DWARF and 12-byte in 64-bit DWARF, See: DWARFv5 <http://dwarfstd.org/doc/DWARF5.pdf> 7.21 Address Range Table).

Known issues:

- The current implementation of `debug_aranges` doesn't support emitting `segment` in the `(segment, address, length)` tuple. I will fix it in a follow-up patch.
