rust: max_width=100, other rustfmt settings. #27071

These are the 12 stable and documented configuration options,
set to their default values.

use_small_heuristics is only stabilized in rustfmt 0.9, so maintain
support for 0.8.x for now by commenting it out.

comment_width is unstable and did nothing, since wrap_comments defaults
to false.

Default values gotten from `rustfmt --print-config default rustfmt.toml`.
