Includes the following minor functional fixes to deno_webgpu:
* Don't throw an error immediately when `create_buffer` is called with invalid usage flags.
* Implement `on_submitted_work_done`.
* Correct validation of GPUExtent3D element count.
* Run without tracing (instead of panic) if the DENO_WEBGPU_TRACE env var is not set.
Fixes#6838
This commit was authored by running the following Nushell script, using
the `nu` binary and the lovely `fastmod` tool:

…and cleaning up `deno_webgpu/`'s Rust compilation errors.
* Change the signature of `wgpu_core::Global::queue_submit` to return
a `(SubmissionIndex, …)` in addition to its current error type.
* Change the control flow of errors in `Queue::submit` to break to the
end of a block. This is similar to what we already do in many APIs in
`wgpu_core`.
* Hoist the scope of the local `submit_index` binding so it can be used
at the point where we need to convert current error paths to also
return the submission index.
Later, we will likely want to avoid actually retrieving a new submission
index so we can minimize the critical section of code. We'll need to
figure out a strategy for returning a valid (but not necessarily unique)
index in the case of failures that prevent successful submission.
* WIP: add cts_runner and deno_webgpu crate
* add test
* remove Cargo.lock
* review comment
* simplify
* fix bugs
* improve cts_runner to work with crowlKats/webgpu-examples
* fix
* remove build.rs
cts_runner binaries are now not portable anymore.
Also startup will now print a bunch of cargo:rerun-if-changed=. This
will be fixed in deno_core.
* remove d.ts
* add original deno license file
