support wcow and lcow with wsl2 backend

[kamkie]

using wsl2 first preview it was possible tu run lcow container in one context using wsl2 backend
and wcow in another context

new docker desktop on wsl2 preview (2.1.5) currently doesn't allow this

Hi @kamkie , you can still do it but you need to switch to windows containers to start windows daemon or switch to linux containers in windows one in launch at startup.
Only the last daemon is relaunched when you start the application.
And there is only context so you need to switch every time you want to redirect cli to the appropriate engine.

it would be really nice if we could use windows containers and --platform switch (like with wcow and lcow) but with wsl2 backend instead of lcow

if this is something that you don't want to implement fell free to close this issue

I'd like to, shall we say, strongly encourage the implementation of this, or if not this - although it is obviously the preferable option - then at least the ability to run Windows and Linux containers simultaneously and switch back and forth between controlling them using docker context .

Being able to mix container types in a single docker/single machine scenario is the key feature of Docker/WSL 2 for me. If that's not supported, there's not all that much to be gained over my previous practice of installing docker both on Windows and inside WSL.
