[DEV TRACING][UPSTREAM] Add support kernel modules & headers as a VHD

[Nevuly]

Latest WSL2 6.6.y kernel update provides instructions for bundle kernel module files into a VHD. But they don't give any details about how to use the generated modules.vhdx. I'm expecting WSL2 team will give us some options in .wslconfig and it will just work out of box.

If so, we can easily implement kernel update with modules via scoop. Users don't have to update kernel module files manually for each distro & each release, which is nice. We don't have to build everything into the kernel then.

Also it's not difficult to bundle kernel headers as a VHD too, it will be more convenient for people who somehow need original kernel headers (e.g. to develop kernel drivers on WSL2).

I do find some instructions to mount VHDX manually via PowerShell/WSL commands, but this requires per-distro setup (e.g., fstab, partition mounting).

In official WSL2 6.6 kernel provides instructions for bundle kernel module package into a VHD.

It looks fine, but It need more information about how to use it in WSL2 environment.

Microsoft added script to generate VHD in below:
