rustdoc: remove `--passes` and `--no-defaults`

- flags no longer function, see #44136
- adjust tests to match new behavior
- removed test issue-42875 (covered regression with --no-defaults)
- moved input-format to removed flags
- move all removed flags to bottom
- note flag removal in command help
- remove DefaultPassOption enum (now redundant with `show_coverage`)
