744: Demonstrate obj loading in the skybox example r=kvark a=kvark
I wanted to see which example is best suited for `typed-arena` demo... and here I am, implementing a completely different unrelated feature. But I think it's useful, still ;)
Model loading is something everybody needs, and for us depending on `obj` in dev-dependencies cost nothing, especially since I'm basically maintaining it.

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?

Deprecates #794 and #793
**Description**
We were often getting this kind of errors when replaying on Linux:

The Vulkan spec states: imageExtent must be between minImageExtent and maxImageExtent, inclusive, where minImageExtent and maxImageExtent are members of the VkSurfaceCapabilitiesKHR structure returned by vkGetPhysicalDeviceSurfaceCapabilitiesKHR for the surface (https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#VUID-VkSwapchainCreateInfoKHR-imageExtent-01274)

It's annoying to work around!

755: Add Instance::poll_all r=kvark a=lachlansneff
`Instance::poll_all` polls all devices. This will be useful for integrating into the winit event loop from a third-party crate.

1206: Convert `PrimitiveState::cull_mode` to `Option<Face>` r=kvark a=yzsolt
**Connections**
Closes#1192
**Description**
`wgpu::CullMode` was an enum with a `None` variant, which would be more idiomatic as an `Option` in Rust.
**Testing**
- `wgpu-rs` builds with the appropriate changes
- `wgpu-native` needs https://github.com/gfx-rs/wgpu-native/pull/71 merged before it can be updated

1191: Buffer zero init test for binding (and use in a compute shader) r=kvark a=Wumpf
**Connections**
Buffer zero init #1159
Buffer zero crash on unused buffer fix#1190
**Description**
Tried to create a player ron file repro case for #1190 but didn't work out quite well (test keeps buffers alive even when I tried to go through an indirection via buffer copies). But with a bit of cleanup the test still felt very useful since it gives more coverage to buffer zero init.
Generally zero init is hard to test since the way to get the result is to map it which is one particular case of requiring zero init. But there's a few ways like in this test here where we look at what modifications a compute shader did to a buffer - since the buffer was not explicitly initialized, the outcome would be different if the compute shader would have seen a buffer without zero init.
Given how few tests there are right now this ofc implicitly tests a bunch of other things ;)

1198: Fix command allocator race condition with maintenance r=kvark a=kvark
**Connections**
Fixes#1196
**Description**
This was a recent change, where I thought it would be more pure to just prepare the pool but not create anything right away. It looked more elegant, but now we see it was flowed.
**Testing**
Not really tested the concurrent aspect of it, but it should work.
Perhaps, we can hook up Loom in the future for this task?

1194: Isolate binding compatibility logic into a separate module r=cwfitzgerald a=kvark
**Connections**
Fixes#1188
**Description**
The actual problem was the following: when a pipeline changed, we used to go through the binding entries and re-bind only those that *became* compatible. However, we were missing ones that were already compatible, but were not activated because they were behind some previously incompatible ones.
So it's not a very complex fix. However, working with the binding code had me concerned that it wasn't isolated enough. It got quite a few issues discovered in it over the time, which only proven the point that it was way too fragile. So I took this opportunity to bring us closer to the world I want wgpu to be in: the world of semi-independent testable components.
This PR makes the binding compatibility checker one of these components. It's fully isolated, has unit tests, fairly straightforward to reason about, and integrates nicely with the render pass logic (without too many generics!). It's more profitable in the long run, I think, to build this kind of architecture versus integration-testing the thing (even at `wgpu` playtest level).
There is less magic overall now: no binding iterator, no fancy chaining, no complex matching. The logic is straightforward, hopefully. And the 40 LOC saved is a good indication of it.
**Testing**
Tested on wgpu-rs examples.

1187: validate for strip_index_format being used with non-strip topology r=kvark a=Wumpf
**Description**
Hit lack of this validation when porting a project to newest wgpu-rs: Accidentally set the strip_index_format for a TriangleList pipeline which left me with a Vulkan validation error (since wgpu decides to set `restart_index` in presence of a `strip_index_format`)
```
VALIDATION [VUID-VkPipelineInputAssemblyStateCreateInfo-topology-00428 (-1077750125)] : Validation Error: [ VUID-VkPipelineInputAssemblyStateCreateInfo-topology-00428 ] Object 0: handle = 0x1ebbfa512a8, type = VK_OBJECT_TYPE_DEVICE; | MessageID
= 0xbfc2d693 | vkCreateGraphicsPipelines() pCreateInfo[0]: topology is VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST and primitiveRestartEnable is VK_TRUE. It is invalid. The Vulkan spec states: If topology is VK_PRIMITIVE_TOPOLOGY_POINT_LIST, VK_PRIMITIVE_TOPOLOGY_LINE_LIST, VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST, VK_PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY, VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY or VK_PRIMITIVE_TOPOLOGY_PATCH_LIST, primitiveRestartEnable must be VK_FALSE (https://vulkan.lunarg.com/doc/view/1.2.141.0/windows/1.2-extensions/vkspec.html#VUID-VkPipelineInputAssemblyStateCreateInfo-topology-00428)
object info: (type: DEVICE, hndl: 2112044208808)
```
(arguably wgpu could be more clever about this and just not set `restart_index`, but that leaves the user code in a non-sense state)
**Testing**
One-off test triggering the error through wgpu-rs.
