Update to Naga 0.19

[Dinnerbone]

It comes out on the 17th hopefully, so opening this now to hopefully get an easy update. Will undraft on release,

Also sneakily includes a fix for a new version of cargo fmt that came out since the last time it was ran on this project.

Tests work on my machine (windows) but CI fails on Ubuntu for... unknown reasons. I don't think it's related to this PR.

thanks! yeah i agree the ci failures are not related. i am not sure what's going on, will investigate properly for the next naga release.

PR is now up to date with 0.19

Locally I experienced a test failure but I can't get it to happen again. Hard to say if it's naga, naga_oil or something else at fault.
