There is currently no way to know which libraries are optional.
Introduce a enable_libs option (close to what we have for drivers) so
that packagers or projects consuming DPDK can more easily select the
optional libraries that matter to them and disable other optional
libraries.

Changes since v5:
- added an entry in the release notes,
Changes since v4:
- moved always_enable earlier for readability,
Changes since v3:
- split non related cleanup changes,
- fixed false positive complaints about disabling mandatory libs by
building the list of always enabled libs, appending this list to
enable_list and checking the disable side,
- updated enable/disable_libs descriptions,
Changes since v2:
- moved the IOVA check for kni build in lib/kni/meson.build,
- reworked deprecated libraries handling by only considering them when
no enable_libs option is set. With this, no need for a default value
in meson_options.txt, yet configurations in the CI must be adjusted,
- moved mandatory libraries check after enable/disable_libs evaluation,
