Fixes#11846.
This PR has three commits:
- The first commit adds an `initializer-suggestions` configuration to
control suggestion applicability when initializers are present. The
following are the options:
- "none": do not suggest
- "maybe-incorrect": suggest, but do not apply suggestions with `--fix`
- "machine-applicable": suggest and apply suggestions with `--fix`
- The second commit fixes suggestions to handle field attributes
(problem [noticed by
@samueltardieu](https://github.com/rust-lang/rust-clippy/pull/13737#discussion_r1859261645)).
- The third commit adds `initializer-suggestions = "machine-applicable"`
to Clippy's `clippy.toml` and applies the suggestions. (Nothing seems to
break.)
