Revive the CTS job

[andyleiserson]

Fixes #6838

Includes some functional changes to make it work, notably:

• Makes access to GPUDevice.lost produce a promise (it did not seem to do so, before). But I don't know how to trigger resolution of the promise when device loss occurs.
• Implements on_submitted_work_done in deno_webgpu similar to how mapAsync is implemented.
• Removes an error that was raised when destroy() is called multiple times.

A pinned CTS version is specified in cts_runner/revision.txt. That version is quite old, but is not changed by this PR, because there is a problem running the latest version in deno. gpuweb/cts#4385 has the fix for that.

Testing
I tested the CTS job in my personal fork of wgpu. We can also verify that the CTS job runs on this PR (based on a label being set). The workflow_dispatch trigger only works once the workflow is merged to main.

I tried a bunch of versions of this, and GitHub kept saying it was an error in the yaml syntax. But I'm not sure if this one is correct, or if it's interpreted as a non-null string that will always be true.

Clippy is probably on to something here:

error: usage of an `Arc` that is not `Send` and `Sync`

    = note: `Arc<DeviceErrorHandler>` is not `Send` and `Sync` as `DeviceErrorHandler` is neither `Send` nor `Sync`
    = help: if the `Arc` will not used be across threads replace it with an `Rc`
    = help: otherwise make `DeviceErrorHandler` `Send` and `Sync` or consider a wrapper type such as `Mutex`

I am going to mark this as a draft and open separate PRs for the functional changes.
