support libmutter-11

[decathorpe]

Yup, It's that time of the year again 😞

A few days ago, mutter 43.alpha has been released with a library bump from libmutter-10 to libmutter-11.

The new version was pushed to Fedora Rawhide earlier today, so as soon as the repositories / ISOs are regenerated tomorrow, it should be a good way to test gala changes that are necessary to support the new version.

Let me know if I can help with build / testing in any way.

It looks like this is still an issue with vapi files copied from elementary/gala#1457 and meson.build updated:

Likely the related upstream commit is this one and a copy paste of elementary/gala#1327 should workaround the issue.
