With the recent release of krunkit 0.2.0, a CLI option was added to
enable nested virtualization on macOS hosts with an M3 or higher. Enable
this by default. If the host does not support this feature, krunkit will
ignore the argument and continue starting the VM.

This is faster and, to my best knowledge, is equivalent to the old code.
Remove the error return (as we don't guarantee stable API here), and
simplify callers.

Recently was trying to start podman machine with krunkit and got:
Error: krunkit exited unexpectedly with exit code 1
which isn't very descriptive. Although this doesn't solve the
issue, it increases the debugability of this error.

One problem on FCOS is that the root directory is immutable, as such in
order to mount arbitrary paths from the host we must make it mutable
again and create these dir on boot in order to be able to mount there.
The current logic was racy as it used one unit for each path and they
all did chattr -i /; mkdir -p $path; chattr -i / and systemd can run
these units in parallel. That means it was possible for another unit to
make / immutable before the unit could do the mkdir. I pointed this out
on the original PR[1] but we never followed up on it...
Now this here changes several things. First have one unit that does the
chattr -i / (immutable-root-off.service), it is hooked into
remote-fs-pre.target which means it is executed before the network
mounts (virtiofs) are done.
Then we have another unit that does chattr +i /
(immutable-root-on.service) which turn the immutable root back on after
remote-fs.target which means all mount are done at this point.
Additionally the automount unit is removed because it does not add any
value for us and it was borken anyway as it used the virtiofs tag as
path so systemd just ignored it.

I'm hitting a bug with 9p when trying to transfer large files.
In RHEL at least 9p isn't supported because it's known to have a
lot of design flaws; virtiofsd is the supported and recommended
way to share files between a host and guest.
Add a new hidden `PODMAN_MACHINE_VIRTFS` environment
variable that can be set to `virtiofs` to switch to virtiofsd.

When running with "log-level=debug" and libkrun as machine provider,
spawn a Terminal to execute "krunkit" to enable users to have full
access to the VMs console for debugging purposes.
Users obtain an interactive, text console with scrollback. It's possible
to interact with both the kernel and GRUB2. To obtain even additional
debugging information, users can add "console=hvc0" to the linux kernel
command line through GRUB2 (it may be worth considering extending the
initial configuration of the VM to add that argument by default).

AppleHV accepts a max 36 bytes for mount tags. Instead of using the fully qualified path for the mount tag, SHA256 the path, and truncate the shasum to 36 bytes.
Also correctly escape dashes in mounted paths.

This PR adds libkrun support to podman machine. This is an experimental feature and should not be marketed yet. Before we unmark the experimental status on this function, we will need to have full CI support and a full podman point release has pased.
This work relies on the fact that vfkit and libkrun share a reasonably (if not perfectly) same API. The --log-level debug option will not show a GUI screen for boots as krun is not capable of this.
