Dallas Strouse c8c5560916 backends/native: Main thread rt-scheduler: experimental feature no more
To paraphrase jadahl: we have a dedicated KMS thread now, which also
has realtime scheduling enabled unconditionally. realtime scheduling
on the main thread isn't too great of an idea, considering GC can
take a hot minute.

And to quote rmader: we most likely won't be able to make the main
thread rt as long as we use GJS and thus have GC.

So let's get rid of it! It's just been breaking things anyways.

This just ignores the setting; we'll fully remove it when GNOME 46
comes around.

<key name="experimental-features"
flags='org.gnome.mutter.MetaExperimentalFeature'>
<default>[]</default>
<summary>Enable experimental features</summary>
<description>
To enable experimental features, add the feature keyword to the list.
Whether the feature requires restarting the compositor depends on the
given feature. Any experimental feature is not required to still be
available, or configurable. Dont expect adding anything in this
setting to be future proof.
Currently possible keywords:
• “scale-monitor-framebuffer” — makes mutter default to layout logical
monitors in a logical pixel coordinate
space, while scaling monitor
framebuffers instead of window content,
to manage HiDPI monitors. Does not
require a restart.
• “kms-modifiers” — makes mutter always allocate scanout
buffers with explicit modifiers, if
supported by the driver. Requires a
restart.
• “autoclose-xwayland” — automatically terminates Xwayland if all
relevant X11 clients are gone.
Requires a restart.
