wgpu 0.17 (#9302)

~~Currently blocked on an upstream bug that causes crashes when
minimizing/resizing on dx12 gfx-rs/wgpu#3967
wgpu 0.17.1 is out which fixes it

# Objective

Keep wgpu up to date.

## Solution

Update wgpu and naga_oil.

Currently this depends on an unreleased (and unmerged) branch of
naga_oil, and hasn't been properly tested yet.

The wgpu side of this seems to have been an extremely trivial upgrade
(all the upgrade work seems to be in naga_oil). This also lets us remove
the workarounds for pack/unpack4x8unorm in the SSAO shaders.

Lets us close the dx12 part of
#8888

related: #9304

## Changelog

Update to wgpu 0.17 and naga_oil 0.9
