* Fix opening renderdoc lib
Renderdoc needs to not be opened by us, but instead open the existing copy.
Unfortunately this requires OS specific flags for opening, plus `libloading`
doesn't have full API coverage currently.
* Added changelog entry for #2930
* Hide RTLD_NOLOAD behind a cfg for unix

* StagingBelt: check for free chunks in the `receiver` as well as `free_chunks`.
Previously, chunks would only be taken from the GPU callback receiver
and put on `free_chunks` during `finish()`. So, there might be chunks
that are actually available for use but wouldn't be used.
Now, we consult the receiver whenever we're about to consult the
`free_chunks`, so the reuse of chunks will be as good as possible (given
the application's uses of operations that trigger `map_async` callbacks).
* Changelog entry.
* Record that the buffer is mapped when its size is zero.
* Avoid internally trying to map a zero-sized buffer if mapped_at_creation is true.
* Add an entry in the changelog.
The versions of wasm-bindgen-cli run by `.github/workflows/publish.yml` must
exactly match the version of `wasm-bindgen` used by `wgpu`. At the moment,
`wgpu/Cargo.toml` specifies `0.2.81`, and our `Cargo.lock` agrees, so
that is what `publish.yml` should mention.
The wgpu web backend uses `()` as `Context::SubmissionIndex`, which is
fine --- WebGPU provides no way to identify individual queue
submissions --- except that Clippy is concerned about us passing
around `()` in the front end as if it were a real value. Instead,
define a new zero-size `wgpu::backend::web::SubmissionIndex` type for
this use.
* Ensure the BufferMapAsyncCallback is always called.
This solves two issues on the Gecko side:
- The callback cleans up after itself (the user data is deleted at the end of the callback), so dropping the callback without calling it is a memory leak. I can't think of a better way to implement this on the C++ side since there can be any number of callback at any time living for an unspecified amount of time.
- This makes it easier to implement the error reporting of the WebGPU spec.
* Update the changelog.
