gtk4 4.6.4+ds-3 source package in Ubuntu

Changelog

gtk4 (4.6.4+ds-3) unstable; urgency=medium

  * d/rules: Stop skipping ngl tests on big-endian machines.
    The ngl renderer no longer exists: it was renamed to gl.
  * d/rules, d/run-tests.sh: Move loop through backends into run-tests.sh.
    This means that if an X11 test fails, we try the Wayland tests (if we
    are running them at all) before failing the build.
  * d/rules: Work around llvmpipe segfault by forcing softpipe on mipsel
    for build-time tests. (Mitigates: #1010838)
  * d/control.in: Move gi-docgen to Build-Depends-Indep.
    We correctly disable the gi-docgen-generated documentation when only
    building architecture-dependent packages.
  * d/control.in: Drop build-dependencies that were only there for gi-docgen.
    Now that we're using the packaged gi-docgen instead of the bundled copy,
    there's no need to depend on its dependencies explicitly.
