Update to wgpu 29 (#7990)

Browse Source 
* [x] I have followed the instructions in the PR template

This updates wgpu to v29 across the egui crate stack.

There a a few API changes due to the requirement to provide a display
handle up front to properly support GLES on linux. I have done my best
to make the api changes as reasonable as possible, but I don't have all
the greater project context, so lmk if things should be done a bit
differently.

I've also updated glow to 0.17 to make cargo deny happy, there are no
source changes. I'm not sure how you want to land these.
