Raspberry Pi camera module v3 support (IMX708)

[leigh-johnson]

Describe your Request The v3 module adds HDR and autofocus, with a dependency on libcamera (which we already distribute along with gstreamer plugin packages).

The v2 module is deprecated and no longer stocked by the vendor we're sourcing kits from.

• [x] Add dtoverlay
• [x] Do we need to rebuild a newer kernel?
• [x] Can we enable/disable autofocus? Can we set focus on the fly using v4l2 control properties?

Looks like the IMX708 drivers were mainlined with Linux kernel 6.1

So the order of operations here should look something like...

• Upgrade Yocto base release to 4.2 (Mickledore), where 6.1 is the preferred kernel version

• Build kernel from: https://github.com/raspberrypi/linux/commits/rpi-6.1.y

• Raspberry Pi firmware rev bcf6e3217f79d4aafe29b836003df5ad90fca399 requires kernel 6.1.25 https://github.com/raspberrypi/firmware/tree/bcf6e3217f79d4aafe29b836003df5ad90fca399

• Verify core applications, especially OctoPrint and Moonraker/Klipper. Mickledore will upgrade Python version from 3.10 to 3.11

Next up: testing release candidates of v0.7.0 (Garnet Mickledore) - all hail.

Took care of some housekeeping related to cloud-init; we're now patched against CVE-2023-1786.

Camera systems are go!

• [x] RPI camera module v3 works with PrintNanny Cam webrtc view
• [x] OctoPrint HLS stream ok
• [x] OctoPrint JPEG snapshot o

mainsail.target is not getting activated when enabling Mainsail via PNOS dashboard, looking into that next.
