1051: Register init-destination buffer in the pending writes r=kvark a=kvark
**Connections**
Fixes#1049
**Description**
At some recent point we introduced the map of destination buffers for copies, and I missed the case where buffers are mapped at creation.
**Testing**
Tested on the test-case in #1049

1008: Add helpers to convert passes to serialized forms r=grovesNL a=kvark
**Connections**
Stuff I needed to fix in the upcoming Gecko WebGPU update.
**Description**
It allows us to use the tracing `Command` more aggressively.
**Testing**
Tested in Gecko, doesn't need testing in wgpu

1000: Elide redundant set_pipeline calls. r=kvark a=Kimundi
**Description**
This adds an check in each `set_pipeline()` call for wether the same pipeline id has already been set previously. This should cause free performance wins for suboptimal usage of the wgpu API, while having neglible overhead otherwise.
An example scenario for where this would be useful is a game that just blindly sets all render state for each object, but has few actually different objects:
```rust
for game_obj in game_objs {
rpass.set_pipeline(...);
rpass.set_bind_group(...);
rpass.set_vertex_buffer(...);
rpass.draw(...);
}
```
**Testing**
Ideally we would have tests that check that pipeline changes have been ellided, but I'm not sure how to write them in the current codebase.
**Future work**
- We could extend this kind of redundant state change detection to most `.set_*` methods on `RenderPass`es.
- If we want to guarantee this behavior in the API, we should also document it.

982: Fix debug markers in render passes (#981) r=kvark a=kazimuth
Hey, that was easy. Didn't change anything in the debug groups markers / command pass markers, since afaict they work correctly.
I didn't add a test here because I'm not sure how to use the `player` testing apparatus, but I figure since I'm just adding a line of code that's already there for compute passes ([here](https://github.com/gfx-rs/wgpu/blob/master/wgpu-core/src/command/compute.rs#L452)) it should be alright. Let me know if there's anything else I should add.
