remove the deprecated options in rustfmt.toml

[guanqun]

The old rustfmt.toml can't work with latest rustfmt. Some of these configs in rustfmt have been either removed or renamed. So updating this file to reflect these changes. This should be a good starting point for our new coding standards in parity.

Awesome! Did you try to run rustfmt against the codebase? What are the results?

There are thousands of lines of changes... Do you want me to create a code review for this?

I created another PR here: #5624

I'd like to get this PR merged, but leave the other one abandoned, unless we agree on a good style. :)

And looks like our parity is not a workspace yet, so only run fmt on parity, not all submodules.

I closed the other PR and hopefully we can get this small changes merged in.

Anything I should fix?

looks good! thanks @guanqun !
