Store the device's queue via a weak ref instead of an ID

• Resolve cycles in wgpu-core using weak references #5120
• add test that verifies that we can drop the queue before using the device to create a command encoder #5211

Description

This is one of the internal uses of IDs instead of Arc/Weak references.

With this PR the Queue has an strong reference to the device and the device has a weak ref to the queue.
I think that to align with the WebGPU spec we should do the opposite (The device owns the queue). However that's more complicated to do this way because of the way the device and queue are destroyed currently (not impossible but more complicated).

This does not quite fix the test from #5211, but it turns the panic into a validation error in create_command_encoder.

Checklist

• Run cargo fmt.
• Run cargo clippy.
• Run cargo xtask test to run tests.
