WSL support

[squirrelsc]

It needs to rebase to previous PR to reduce commits. The work is tested with local and Azure platforms. I will add document later.

See details in commits and document.

@LiliDeng it's ready for reviewing

I have tested it against azure and libvirt platform to confirm there is no regression bring in. And I may post some stupid comments/questions, since I don't know the WSL testing in lisa deeply.

Thank you, Lili! All comments are valuable. Any existing tests should be able to run with WSL node ideally, but we are focusing on single node tests. There must be some test cases are not supported, like if the features are used.

I will fix LTP data disk dependency. In the mean time, you can test with cpu or other simple test cases.

I test it in azure platform with image MicrosoftWindowsServer WindowsServer 2022-datacenter latest
And encounter the issue mentioned here

this approach works (I didn't try the other approaches)

wsl --set-default-version 1
wsl.exe --install Ubuntu
wsl --set-default-version 2

If azure vm with NestedVirtualization feature, current code works perfectly.

Yes, forget to mention, it needs nested virtualization vm sizes.
