Mutter release 46.2

[Daniel van Vugt]

[ Impact ]

Release Mutter 46.2 to Oracular and eventually SRU to Noble.

[ Test Plan ]

Complete the test case from
https://wiki.ubuntu.com/DesktopTeam/TestPlans/Mutter

[ Where problems could occur ]

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 ]

[Daniel van Vugt (vanvugt)]

I had intentionally omitted Noble because it's not yet clear if it will get the full 46.2 due to the 46.1 issue... But I guess even releasing a cut down version would still be tracked here.
