Miguel Ojeda b2bf463ed9 docs: rust: improve main page introducing a "Code documentation" section
Clean the "Rust" main page by introducing a 'Code documentation" section
to separate it from the rest of the text above.

In addition, introduce the "Rust code documentation" term, which may be
clearer than referring to a potentially unknown tool.

Furthermore, for the HTML case, homogenize both `rustdoc` and
non-`rustdoc` cases and use the term introduced above instead.

Then, always generate the pregenerated version part, since now there
is a section that is always generated and thus makes sense to do so.

Finally, finish the new section with a link to more details about the
Rust code documentation.

The intention is that:

  - The non-HTML case mentions the code documentation too, making it
    more prominent for readers of non-HTML docs.

  - Both HTML cases read more naturally.

  - The pregenerated version is always mentioned, since it is likely
    useful for readers of non-HTML docs.

====
Documentation related to Rust within the kernel. To start using Rust
in the kernel, please read the quick-start.rst guide.
The Rust experiment
-------------------
The Rust support was merged in v6.1 into mainline in order to help in
determining whether Rust as a language was suitable for the kernel, i.e. worth
the tradeoffs.
Currently, the Rust support is primarily intended for kernel developers and
maintainers interested in the Rust support, so that they can start working on
abstractions and drivers, as well as helping the development of infrastructure
and tools.
If you are an end user, please note that there are currently no in-tree
drivers/modules suitable or intended for production use, and that the Rust
support is still in development/experimental, especially for certain kernel
configurations.
Code documentation
------------------
Given a kernel configuration, the kernel may generate Rust code documentation,
i.e. HTML rendered by the ``rustdoc`` tool.
.. only:: rustdoc and html
This kernel documentation was built with `Rust code documentation
<rustdoc/kernel/index.html>`_.
.. only:: not rustdoc and html
This kernel documentation was not built with Rust code documentation.
A pregenerated version is provided at:
https://rust.docs.kernel.org
Please see the :ref:`Code documentation <rust_code_documentation>` section for
more details.
