Update mutter to 42.1

[Jeremy Bícha]

Impact
------
There is a new bugfix release in the stable 42 series. This is a bigger update with lots of bugfixes as the first bugfix release in the 42 series.

https://gitlab.gnome.org/GNOME/mutter/-/blob/42.1/NEWS

Test Case
---------
sudo apt install budgie-desktop gnome-session gnome-shell-extensions
Install the update.
Log out.
Select your name on the login screen.
Click the gear button to choose a session to log in to.
Finish logging in.

Verify that things continue to work well for all these sessions:
Budgie
GNOME
GNOME Classic
Ubuntu
Ubuntu on Xorg

(There are more specific test cases for some of the other bugs fixed with this update.)

What Could Go Wrong
-------------------
Mutter is an essential component of the default Ubuntu desktop and for the desktop used by Ubuntu Budgie.

A severe enough bug could mean that people are unable to use their desktop version of Ubuntu.

Smaller bugs could interrupt people's workflows.

mutter is part of GNOME Core and is included in the GNOME micro release exception

Other Info
----------
This update should not reach jammy-updates until these updates are fully phased in jammy-updates to avoid a known testview scrolling bug in apps like gedit and gnome-text-editor

[Mauro Gaspari (ilvipero)]

Ubuntu Budgie 22.04 LTS (Xorg)
Kernel 5.15.0-33-lowlatency
libmutter-10-0 installed from proposed

Budgie DE is behaving well, feels snappy and fast. No issues to report.

Tests performed:
- Check budgie panels and applets.
- Move between virtual workspaces.
- Window tiling using mouse.
- Window tiling using shuffler shortcuts, layouts.
- Window minimize and maximize animations.

Confirmed Mauro's observations for Ubuntu Budgie on a Ryzen 4700 setup

libmutter-10-0 42.1-0ubuntu1

This pulled in gtk3 and other packages as well

Similar tests as Mauro - no adverse observations to report

[Sam Lane (samlane00)]

Also using Ubuntu Budgie 22.04

I have also been testing this on two separate laptops - both are Thinkpad T560, one with Intel, one with Nvidia graphics. Ran similar tests to Mauro with no issues found.

GNOME
GNOME Classic
Ubuntu
Ubuntu on Xorg
