[v3,0/3] dts: API docs generation

  The generation is done with Sphinx, which DPDK already uses, with
slightly modified configuration of the sidebar present in an if block.

Dependencies are installed using Poetry from the dts directory:

poetry install --with docs

After installing, enter the Poetry shell:

poetry shell

And then run the build:
ninja -C <meson_build_dir> dts-doc

The patchset contains the .rst sources which Sphinx uses to generate the
html pages. These were first generated with the sphinx-apidoc utility
and modified to provide a better look. The documentation just doesn't
look that good without the modifications and there isn't enough
configuration options to achieve that without manual changes to the .rst
files. This introduces extra maintenance which involves adding new .rst
files when a new Python module is added or changing the .rst structure
if the Python directory/file structure is changed (moved, renamed
files). This small maintenance burden is outweighed by the flexibility
afforded by the ability to make manual changes to the .rst files.

v2:
Removed the use of sphinx-apidoc from meson in favor of adding the files
generated by it directly to the repository (and modifying them).

v3:
Rebase.
