Since commit 1bf70334 "tests/runner: Make test runner use the headless
backend", tests are run with the native backend in headless mode, which
will attempt to open each GPU and show a warning (fatal during tests)
if it cannot.
However, in headless mode we might not be logged in on any seat (for
example we might be logged in via ssh instead), which means we might
legitimately not have permission to use any GPUs, even if they exist.
Downgrade the warning to a debug message in this case.

The catch option makes test run via 'catch'[1], which will log
backtraces whenever an abort or segmentation fault happens in any of the
subprocesses. The aim is to enable this when running in CI to help
debugging crashes that only tend to happen in CI.
While it's possible to wrap the whole meson command in 'catch', doing so
doesn't cover the KVM tests, so this option is added instead that covers
both cases.

Until recently, mutter-test-runner called into libraries that
indirectly depend on (mutter's fork of) Clutter, but did not actually
call into Clutter itself. Commit 1bf70334 "tests/runner: Make test
runner use the headless backend" gave it a direct call into Clutter,
which means the runtime linker will fail unless the executable's
RUNPATH is sufficient to find Clutter.
For future-proofing, do the same for the other test executables.

This is a followup to GNOME/mutter!1578
This commit does a couple of things to avoid creating multiple
pipelines per commit.
First, it avoid catch all `when: manual` rules, which might
end up matching custom variables set which might potentially
not be handled.
Secondly it reworks the `workflow:rules:` and the pipeline guard
rules to avoid duplicate pipelines as the gitlab documentation
suggests.
Last, it switches from yaml anchors to the new `reference` gitlab
keyword which is more flexible.

This adds the 4 new connector types that mutter didn't know about from
drm_mode.h in the kernel.
Noticed because mutter kept crashing when plugging in a USB-C adapter to
use an external monitor.

When we e.g. generate switch configs (i.e. the ones from pressing the
Super+P or the switch-config key on laptops), try a bit harder to find a
"good" monitor scale.
With "good", it means pick a scale that was used in a previous
configuration. In practice, this means that if you for example have
configured your external monitor to use a specific scale, then pressed
e.g. "built in only", and then switched back to e.g. "external only" or
"linear", the generated configuration will use the scale that was
previously configured.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2479>
If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.
This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.

This will eventually help with better hueristics for finding a good
scale. It currently doesn't change much, but the helper will later gain
more functionality that will also help when coming up with mirroring
configs.

The resulting logical monitor was eventually marked as primary anyway,
but without the config being marked as such, various primary properties
was not set e.g. the one on the MetaOutput. Also, tests would fail.
