wgpu: Update to 0.10

[PolyMeilex]

• blocked by: Update to wgpu 0.10 hecrj/wgpu_glyph#73 (no longer blocking)
• Opengl backedn of wgpu now works as expected in iced (I never managed to run it in prev versions, but now it works)
  • EDIT: nope, never mind, on my second device it does not work at all, so it's still unstable (at least on linux)
• Images in OpenGL are for some reason black, I will investigate this a little bit more soon.
• Wgpu SwapChain not longer exists, so surface was added as an argument to draw() in compositor trait, wgpu implementation of compositors uses () as a SwapChain type now.

Fixes #933.

Please file issues about OpenGL backend!

• [hlsl-out] Implement switch statement gfx-rs/naga#1265 Is now blocking this PR, as without it DX12 backend does not work (no longer blocking)
• Also, one of my users confirmed that this update fixes WGPU 0.9 breaks Image rendering [AMD Integrated] #933 for him, on 2 different AMD GPUs

Thank you @PolyMeilex! 🎉

I think this is ready to merge!

After update of deps (maybe new naga?), text is no longer rendered in OpenGL backend... I'm kinda tired of debugging OpenGL backend, if I'll find some free time I will try to find a reason for this and report it (probably upstream)
