v3d: Wrong colors (pink) in videos in Firefox (likely YUV->RGB shader issue)

In Firefox with GL rendering some videos show pink colors - likely because some shader issue.

STR:

• on Raspberry Pi 4 with 64 bit Raspberry Pi OS (Debian bullseye) + apt install -t testing libegl-mesa0 --no-install-recommends (Mesa 22.2.0~rc1) from bookworm
• use latest Firefox nightly (https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/I8mEK8w7SWWI67ONStnZcA/runs/0/artifacts/public/build/target.tar.bz2 from https://treeherder.mozilla.org/jobs?repo=try&revision=15d1f32894118ed05e6108f100cd04f819f6881f&selectedTaskRun=I8mEK8w7SWWI67ONStnZcA.0)
• turn on GL rendering (about:config -> gfx.webrender.all:true)
• video link: https://youtu.be/1La4QzGeaaQ?t=20

Notes:

• Firefox bug https://bugzilla.mozilla.org/show_bug.cgi?id=1784327
• This is currently the last know bug to block GL rendering by default \o/ (therefor it would be absolutely lovely to get a fix into 22.2 ;) )
