this patch changes how the detection of wsl works.
The old way of using wsl --status command output to detect some missing features required by WSL is not fully reliable.
WSL checks if the wsl feature is enabled and if the vmcompute service do exist. However, this is not enough to identify if the virtual machine platform feature is enabled. The vmcompute service could exist because it has been installed by other tools or it could exist but being stopped.
The way proposed by this patch is to try execute the import command and,
if it fails, check the error and if it is related to the Host Compute
Service try to install all features required by WSL.
The flow is the same as before, the user is asked to execute the podman
machine init command with elevated privileges. Eventually, after
enabling WSL and VMP features, the user is asked to reboot the machine.
When the machine restarts, the powershell gets invoked again and execute
the command init.
The code also fixes some issues that could cause misbehaviors when
invoking recursively the elevated shell, like an unreleased lock, or a
missing file.
