Rollup merge of #46787 - varkor:contrib-6, r=QuietMisdreavus

Add an option to allow rustdoc to list modules by appearance

The `--sort-modules-by-appearance` option will list modules in the
order that they appear in the source, rather than sorting them
alphabetically (as is the default). This resolves #8552.
