sync sdformat 9.3.0+ds-3 (universe) from Debian unstable (main)

[Jose Luis Rivero]

Asking for a FFe here since upstream is specially interested into having changes in 9.3.0 in the latest Ubuntu which fixes an important behavior bug, see: https://github.com/osrf/sdformat/issues/367

Attached:
  * Changelog entry from 9.2.0 to 9.3.0
  * pbuilder log - Although I setup a PPA, it can be checked here: https://launchpadlibrarian.net/501751526/buildlog_ubuntu-groovy-amd64.sdformat_9.3.0+ds-3_BUILDING.txt.gz
  * debdiff - Although the PPA I think provides one https://launchpadlibrarian.net/501750879/sdformat_9.2.0+dfsg-4_9.3.0+ds-3.diff.gz

Testing:
I've used our buildfarm to inject the packages created by my testing PPA in a Groovy docker container. Installation is good, smoke test starting up Gazebo (main consumer of sdformat) is also sane. (build fail is related to docker + alsasound nothing to do with this bug).

sdformat (9.3.0+ds-3) unstable; urgency=medium

  * Not ready for compat 13:
    CMAKE_SKIP_INSTALL_ALL_DEPENDENCY=ON kills the arch:all build
