### Description This change allows the `WebGpuContext` class to be released after all active inference sessions are released. This will cause: - for default context (ID=0), the underlying `wgpu::Device` and `wgpu::Adapter` to be released, together with all resources created by the Device. - for custom context (ID>0), the reference counts of passed in Instance, Adapter and Device will decrement correctly.
