8b8036a66e gpudev: introduce GPU device class library
In heterogeneous computing system, processing is not only in the CPU.
Some tasks can be delegated to devices working in parallel.

The new library gpudev is for dealing with GPGPU computing devices
from a DPDK application running on the CPU.

The infrastructure is prepared to welcome drivers in drivers/gpu/.

0a91cdd486 doc: add flow API features tables
The NICs overview table lists all supported features per driver.
There was a single row for "Flow API",
although rte_flow is composed of many items and actions.

The row "Flow API" is replaced with two new tables for items and actions.

Also, since rte_flow is not implemented in all drivers,
it would be ugly to add empty sections in some files.
That's why the error message for missing INI section is removed.

The lists are sorted alphabetically.
The extra files for some VF and vectorized data paths are not filled.

aa9cb78f66 doc: fix sphinx rtd theme import in GHA
If the rtd theme is available, passing it by name is enough to select
it. Sphinx itself recognises the "sphinx_rtd_theme" name as a special
case and tries to find its path automatically.

On the other hand, passing a html_theme_path makes sphinx parse all
themes availables in this path, which in some environment (like GHA) is
/usr/share and makes sphinx error on the first zipfile it finds (in GHA,
some Azure CLI thingy) that has no sphinx theme in it.

7bda955f72 doc: allow external build
Currently, when building sphinx documentation, the build will only
succeed if being run from the build system, because the conf.py script
expects DPDK_VERSION environment variable to be set, and crashes if it
is not.

However, there are certain external tools (such as sphinx documentation
preview extensions for certain IDE's) that use live preview and thus
rely on running their own sphinx commands. In these cases, it is useful
to permit building sphinx documentation without specifying the
DPDK_VERSION environment variable. The version string is the only thing
preventing manual sphinx build commands from working.

Fix the conf.py to use "None" as a version string in cases when
DPDK_VERSION environment variable is not set.

028c57407d doc: make sphinx errors more visible
When running Sphinx through ninja, the wrapper configured in meson
redirects stdout to a log file.

Currently these three tools had docs that were compatible "enough" to
make up for a reasonable manpage.
- testpmd
- dpdk-pdump
- dpdk-procinfo

Since a man page should be installed along the binary they are not
installed in install-doc but install-runtime insteade. If not explicitly
built by the "doc-guides-man" target before calling install-runtime
there is no change to the old behaviour.

9db3f52126 doc: generate NIC overview table from ini files
Convert the NIC feature table in the overview doc into a set of ini
files and add functions into the Sphinx conf.py file to auto-generate
them back into an RST table.

The reason for doing this is to make it easier for PMD maintainers to
update the feature matrix that makes up the table and to avoid
frequent and hard to resolve conflicts in doc/guides/nics/overview.rst.

A NIC/PMD feature matrix is now an ini file like the following:

    $ head doc/guides/nics/nic_features/i40e.ini
    ;
    ; Features of the i40e network driver.
    ;
    [Features]
    Link status          = Y
    Link status event    = Y
    Rx interrupt         = Y
    Queue start/stop     = Y
    ...

The output RST table matches the existing table with the column
headers sorted.

This change adds automatic figure references to the docs. The

* Changes image:: tag to figure:: and moves image caption
  to the figure.

* Adds captions to figures that didn't previously have any.

* Un-templates the |image-name| substitution definitions
  into explicit figure:: tags. They weren't used more
  than once anyway and Sphinx doesn't support them
  for figure.

* Adds a target to each image that didn't previously
  have one so that they can be cross-referenced.

* Renamed existing image target to match the image
  name for consistency.

* Replaces the Figures lists with automatic :numref:
  :ref: entries to generate automatic numbering
  and captions.

* Replaces "Figure" references with automatic :numref:
