Make feature(doc_auto_cfg) work ()
# Objective

- In  `![cfg_attr(docsrs, feature(doc_auto_cfg))] `was added. But
to apply it it needs `--cfg=docsrs` in rustdoc-args.


## Solution

- Apply `--cfg=docsrs` to all crates and CI.

I also added `[package.metadata.docs.rs]` to all crates to avoid adding
code behind a feature and forget adding the metadata.
