Resource Saver mode / pausing causes WSL to freeze

[SunMar]

Description

See microsoft/WSL#11066, when cgroupv2 is used (either through changes in .wslconfig like setting autoMemoryReclaim=true or always as of WSL >= 2.5.1 since they removed cgroupv1 support) and Docker Desktop is paused or enters Resource Saver mode, WSL will hang until Docker Desktop is resumed.

Reproduce

1. Upgrade to WSL 2.5.1
2. Open a WSL terminal
3. Pause the Docker Desktop Engine
4. Try to do anything in your WSL terminal, it'll be non-responsive
5. Resume the Docker Desktop Engine
6. Terminal becomes responsive again

Expected behavior

WSL remains responsive and working normally.
