[ObjectYAML][DWARF] Support emitting the .debug_aranges section in ELFYAML.

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

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.
