[FFe] Raspberry Pi 5 support

Status changed to 'Confirmed' because the bug affects multiple users.

The rpiboot package can be skipped for now; according to upstream the updated package won't be ready at release. The separate bug LP: #2032178 will track updates if/when I can get the uploaded.

FFe for linux-firmware-raspi in LP: #2037634

FFe for gpiozero in LP: #2037637

FFe granted for the remaining packages

Debdiff with squash of https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25450

Briefly tested on Pi 5, 4 and 400. Desktop comes up and glx and vulkan are accelerated.

libcamera is not shipped on the images, and will be SRUed once tested.

Added text to the release notes [1] detailing Pi 5 support, including the planned SRU of libcamera support. Can others double-check the raspberry pi sections look reasonable, and let me know if we want to mention anything else specific?

I've also updated the "known issues" section, removing a couple of bits (totem now works and the audio output selection is now sane out of the box), and adding others (slide corruption on the pi4 during installation). Again, if there's anything missing that should be mentioned please either let me know or feel free to add it yourself!
