webgpu: Update wgpu and revamp computepass (#32575)
* Do not wait on drop, but rather wake poller thread * Update wgpu and render stuff * Set some good expectations * Update wgpu again * handle IPC error as warning * More good expectations * Some more expectations CTS does not match the spec: https://github.com/gpuweb/cts/issues/3806 * This expectations are due to other changes in servo also happening on main * Explain error_command_encoders and remove RefCell around it * fixup * store validness of passes * More good expectations * More docs * this assert is wrong * This is even more right per CTS/spec Only Command encoder state errors are allowed here, but wgpu does not exposes them. * More good expectations * One bad expectation * Fix my english
