Currently blocked on https://github.com/gfx-rs/wgpu/issues/5774
# Objective
Update to wgpu 0.20
## Solution
Update to wgpu 0.20 and naga_oil 0.14.
## Testing
Tested a few different examples on linux (vulkan, webgl2, webgpu) and
windows (dx12 + vulkan) and they worked.
---
## Changelog
- Updated to wgpu 0.20. Note that we don't currently support wgpu's new
pipeline overridable constants, as they don't work on web currently and
need some more changes to naga_oil (and are somewhat redundant with
naga_oil's shader defs). See wgpu's changelog for more
https://github.com/gfx-rs/wgpu/blob/trunk/CHANGELOG.md#v0200-2024-04-28

# Objective
CI is currently broken because of `DiagnosticsRecorder` not being Send
and Sync as required by Resource.
## Solution
Wrap `DiagnosticsRecorder` internally with a `WgpuWrapper`.
# Objective
It's useful to have access to render pipeline statistics, since they
provide more information than FPS alone. For example, the number of
drawn triangles can be used to debug culling and LODs. The number of
fragment shader invocations can provide a more stable alternative metric
than GPU elapsed time.
See also: Render node GPU timing overlay #8067, which doesn't provide
pipeline statistics, but adds a nice overlay.
## Solution
Add `RenderDiagnosticsPlugin`, which enables collecting pipeline
statistics and CPU & GPU timings.
---
## Changelog
- Add `RenderDiagnosticsPlugin`
- Add `RenderContext::diagnostic_recorder` method
