krunkit libkrun virglrenderer: new ports

[tsujp]

Description

Three (3) new ports:

1. krunkit
2. libkrun
3. slp's fork of virglrenderer with required patches for libkrun since these are not merged into virglrenderer upstream.

krunkit allows running VMs on macOS using Hypervisor.framework with hardware accelerated graphics using Venus.

Podman can also use krunkit as a driver instead of the default applehv (Virtualization.framework). If you configure Podman to use krunkit you can run hardware accelerated graphics workloads within the VM (and thus containers) Podman manages on your macOS hosts.

libkrun allows use of more modern versions of virtio and has some advanced networking features (although the latter is not enabled by default nor available at all as I cannot be bothered).

There are a few questions I have regarding this:

1. I plan to add a libkrun variant to the Podman port, this would simply add krunkit as a runtime dependency. Strictly speaking uninstalling krunkit would not break Podman as Podman executes the binary krunkit when configured to use it. It does feel nicer to be able to install Podman with krunkit in one go though. Shall I add said variant?
2. The version of virglrenderer here is slp's fork as already mentioned. Would you prefer I change the Portfile to use upstream virglrenderer and add a libkrun variant to virglrenderer which uses slp's or shall we leave the Portfile as-is only use slp's for now? In the former case how does one specify a variant in build_run?

Once those questions have answers I can do some final cleanup on the Portfiles (as I've left the TODOs in so I do not forget).

Verification

Have you

• followed our Commit Message Guidelines?
• squashed and minimized your commits?
• checked that there aren't other open pull requests for the same change?
• checked your Portfile with port lint?
• tried a full install with sudo port -vst install?
• tested basic functionality of all binary files?

thanks for the submissions @tsujp. I've left a few comments, they apply to all ports.

Also, each ports should be in a different commit please.

please remove unneeded comment

It might be useful for now though as that's how the software should be built? Makes it easier to view those files as (if) things change?

Changes made; requested re-review.

I note that sudo port -vst install krunkit does not work (the -t trace flag is the culprit), but sudo port -vs install krunkit works fine.

It fails around extracting virglrenderer (as of course it prompts to install dependencies). I'm very tired right now so I'm not sure why or if it's actually important?

sudo port -vs install krunkit installs krunkit, libkrun, and virglrenderer fine and Podman can correctly use krunkit and there appears to be the graphics drivers in the VM at /dev/dri which indicates all is working.
