Title:
  [regression] GNOME 46/47 dropped support for Xilinx Mali graphics

Status in Mutter:
  Fix Released
Status in mutter package in Ubuntu:
  Fix Released
Status in mutter source package in Noble:
  Fix Committed
Status in mutter source package in Oracular:
  Fix Released

Bug description:
  [ Impact ]

  Xilinx Mali support was originally written for GNOME 42 but it has
  bitrotted since then. We need to apply a few fixes to get it working
  again in GNOME 46 (Ubuntu 24.04 LTS) and later:

  * https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4019 or
    https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4021
  * https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4036

  [ Test Plan ]

  1. Log into an Ubuntu (GNOME + Wayland) session on Xilinx hardware.
  2. Verify you can log in, there are no obvious rendering failures and that it 
really is a Wayland session (environment XDG_SESSION_TYPE=wayland and 
WAYLAND_DISPLAY=wayland-0).

  [ Where problems could occur ]

  The Mutter/GNOME startup procedure had to be modified for this fix as well as 
some texture format parameters. So there is a small risk to:
  (a) The ability of any machine to log into a Wayland session; and
  (b) Rendering correctness once logged in.
