Missing image dimensions / orientation of avif files

[cgundermann]

Hello,
when I upload avif files in the panel, the resulting uploads don't have any infos about dimension or orientation.
Is it possible to add that, so that I can use file methods like width(), height() and orientation() etc...?

(Ps: sorry if in advance, if this has been brought up before - couldn't find any related issue.)

To reproduce

1. Go to 'Panel'
2. Upload an .avif file somewhere
3. See file info

Having raised PHP requirement to 8.1 we can actually do that!

I have to correct myself though: only seems to work on php 8.2 without compiling special version of php
