Fix VideoCapture not able to read AV1 encoded files on Linux

[ladaapp]

Hi, this is an attempt to fix #908 as AV1 encoded files are pretty common nowadays. My assumption is that there is no av1 decoder available in the official wheel as the same works just fine using opencv-python from ArchLinux build against their ffmpeg build.

On Windows av1 decoding works but not on Linux using the official wheels. I am not sure but I assume there is some kind of fallback mechanism which then uses Windows-native frameworks for decoding which is not available on Linux hence it fails on Linux using ffmpeg backend.

Didn't adjust the arm images yet, wanted to get some feedback first if I'm going in the right direction here. Waiting for the CI to run through to create a wheel I can test if this actually fixes the issue 🤞
edit: looks like CI doesn't run without approval by maintainers, so changed to ready-for-review

fixes: #1205
fixes: #908

I also added the fix for #1205

When building the wheel locally I can see the fonts being picked up and being added to the wheel so this should fix it:

  adding 'cv2/qt/fonts/DejaVuSans-Bold.ttf'
  adding 'cv2/qt/fonts/DejaVuSans-BoldOblique.ttf'
  adding 'cv2/qt/fonts/DejaVuSans-ExtraLight.ttf'
  adding 'cv2/qt/fonts/DejaVuSans-Oblique.ttf'
  adding 'cv2/qt/fonts/DejaVuSans.ttf'
  adding 'cv2/qt/fonts/DejaVuSansCondensed-Bold.ttf'
  adding 'cv2/qt/fonts/DejaVuSansCondensed-BoldOblique.ttf'
  adding 'cv2/qt/fonts/DejaVuSansCondensed-Oblique.ttf'
  adding 'cv2/qt/fonts/DejaVuSansCondensed.ttf'
  adding 'cv2/qt/plugins/platforms/libqxcb.so'

(only needed for the manylinux 2_28 image, manylinux2014 does not not remove dejavu-sans when uninstalling libpng (and doesn't have a yum mark or autoremove option)

The CI currently fails as the image is not available on that image repository. Not sure I can fix that chicken/egg problem. Not sure, but I think you have to continue here and build and push these image to the quay.io/opencv-ci repository as I wouldn't have permissions to do that. Not sure how these docker images are updated, doesn't seem to be automated within this repository here. So your assistance would be appreciated.
