Implement WebGPU ErrorScopes <!-- Please describe your changes on the following line: --> This PR covers the following- 1. update wgpu-core (Rustify `RenderPipelineDescriptor`) 2. Add initial implementation of `pushErrorScope` and `popErrorScope`. 3. Use existing `BGL` if an equivalent already exists. A brief explanation of the ErrorScope Implementation- 1. We store `HashMap<u64, ErrorScopeInfo>` in `GPUDevice`. `ErrorScopeInfo` is a new struct used to store all necessary info for an ErrorScope. 2. We simultaneously store `Vec<u64>` to keep track of the ErrorScope hierarchy. `next_scope_id` is used to get the `scope_id` for a new Scope. 3. We send the `scope_id` of top-level scope to the server in the message for an operation. The server performs the operation and sends back the scope_id with the result message (only if a scope_id was sent from the client. Otherwise no message is sent.). 4. We store a `HashMap<WebGPUDevice, Dom<GPUDevice>>` in `GlobalScope` to access them from `ScriptThread`. 5. While creating a `GPUDevice` we send the `PipelineId` of the pipeline it was created in so that when the server send the response, we can access the device from the GlobalScope of that Pipeline. 6. We generate the relevant `GPUError` in `GlobalScope`(if required) can call the necessary fn in `GPUDevice`. This implementation is pretty rough and not complete at all. Broadly the following cases aren't handled at the moment- 1. ErrorFilter is not checked when an error is captured. 2. We don't propagate an error to enclosing scope if a scope did not capture it. 3. `UncapturedErrorEvents` is not implemented. As for Equivalent BGLs we now store `Vec<(Vec<wgt::BindGroupLayoutEntry>, Dom<GPUBindGroupLayout>)>` in `GPUDevice` and compare `Vec<wgt::BindGroupLayoutEntry>` for new BGL with the existing ones and return one if it is found. Otherwise a new one is created and an entry added to the `Vec`. r?@kvark --- <!-- Thank you for contributing to Servo!
