This change adds a bunch of options that GNU readelf supports. There are two breaking changes, although only one breaking change affects `llvm-readobj`:

- Add --all (implies --file-header, --program-headers, etc.)
- [Breaking for readobj/readelf] -a is --all instead of --arm-attributes
- Add --file-header as an alias for --file-headers
- Add --sections-headers as an alias for --sections
- Add --relocs as an alias for --relocations
- Add --dynamic as an alias for --dynamic-table
- Add --segments as an alias for --program-headers
- Add --section-groups as an alias for --elf-section-groups
- [Breaking only for readelf] When invoked as `llvm-readelf`, -s is --symbols instead of --sections
