Mount a drive into WSL distro owned by a restricted user

**Is your feature request related to a problem? Please describe.**
I use Windows and WSL as a restricted user. However, mounting drives is only possible for Windows elevated admin account.
I have access to admin account. However, it does not have access to restricted user's WSL distrubutions.

**Describe the solution you'd like**
A way to mount a drive into restricted user WSL distributions, given user has access to elevated admin account.

**Additional context**

Restricted user:
```
C:\Users\User>wsl.exe -l -v
NAME STATE VERSION
* Ubuntu Running 2
Alpine Stopped 2
Ubuntu-20.04 Stopped 2

C:\Users\User>wsl.exe --mount \\.\PHYSICALDRIVE1 --partition 1
Administrator access is needed to mount a disk.
Error code: Wsl/Service/AttachDisk/WSL_E_ELEVATION_NEEDED_TO_MOUNT_DISK
```

If Admin has no installed distributions:
```
C:\Windows\system32>wsl.exe --mount \\.\PHYSICALDRIVE1 --partition 1
This operation is only supported by WSL2.
Error code: Wsl/Service/AttachDisk/WSL_E_WSL2_NEEDED

C:\Windows\system32>C:\Users\User\AppData\Local\Microsoft\WindowsApps\wsl.exe -l -v
Windows Subsystem for Linux has no installed distributions.

...
```

If Admin has installed distributions, mounting succeeds for Admin but disk is only visible in Admin's distributions.

**Versions**
