1417: Split the tracker into stateful/stateless to reduce the overhead r=cwfitzgerald a=kvark
**Connections**
Implements https://github.com/gfx-rs/wgpu/issues/1413#issuecomment-851604344
Reduces the overhead for resource tracking in the Animometer benchmark by up to 50%.
**Description**
We used to use the full tracker set on the usage scopes associated with compute/render passes. A resource tracker has 2 responsibilities: ensuring the resource is held alive, and validating and recording the state transitions. This PR exploits the fact that the latter responsibility is only applicable for buffers and textures. So doing all the lifetime tracking for a pass is a waste: we can instead just attach the lifetimes to the parent command buffer, straight.
In the Animometer benchmark, there is one large buffer, and thousands of bind groups pointing to different offsets into it. The old code would fill up the pass tracker with those bind groups, and then merge it into the command buffer tracker. The new code would just fill up the command buffer tracker instead. Since there is only one buffer, the pass tracking becomes much lighter.
**Testing**
Untested. It would be nice to have some benchmarks here, possibly after #1397 ?

1403: Trace render passes before they are ran r=cwfitzgerald a=kvark
**Connections**
Follow-up to #1245
**Description**
We want the API traces to reproduce issues. Previously, we moved all the resource creation to happen after the trace is written.
This PR follow-up by also recording the render pass commands even in the case where one of them triggers a validation error.
Another big part of the PR now is handling the command buffers that failed for some reason. The submission is skipping them now instead of erroring the whole thing.
**Testing**
Tested manually on wgpu-rs examples

* Add command buffer fill buffer method
* Added test for buffer fill
* Added image clear + test
* image/buffer clear methods are now pure clear to zero
* fix cargo clippy & int type issues
* clear buffer alignment is now given by COPY_BUFFER_ALIGNMENT
* joined buffer/image clear player tests
* ImageSubresourceRange is now used in TextureViewDescriptor
- Rename `ColorAttachmentDescriptor` to `RenderPassColorAttachment`
- Rename `DepthStencilAttachmentDescriptor` to `RenderPassDepthStencilAttachment`
- Rename `attachment` fields on both attachments to `view`

1210: Reset the bindings on the push constant change r=wumpf a=kvark
**Connections**
Fixes#1207
(unconfirmed!)
**Description**
I was able to replay the trace in #1207 without validation errors, so I looked deeper into what might have gone wrong.
The code isolated in #1194 looks great. However, the calling code's handling of push constants might have changed a bit.
And I see that the trace uses push constants, so here is what happened, I think:
- layout A was set, expecting bind group layouts X and Z
- bind groups X and Y where bound
- layout B was set, expecting bind group layout X and Y. We see that Y group can now be bound, so we do this. The old logic in this case wasn't considering the push constants in any way, it would only consider them if bind group layouts didn't change, erroneously.
- layout B has different push constant ranges...
So it's a one-line fix now, which I'm hoping is correct.
**Testing**
Not tested
@Wumpf would you be able to check this?
