feat(linux/wlr): Implement ext-image-copy-capture

[Dregu]

I'm putting this draft up simply because these linux prs keep popping up every day and by monday three more people will have implemented this probably, so it would be silly to keep it to myself when it's already pretty much done.

Description

Adds the ext-image-copy-capture protocol as primary backend for the wayland capture method, but keeps wlr-screencopy as a fallback, as it is still slightly better supported. Also supports actual output names in output_name, like that other pr.

• Implements ext-image-copy-capture-v1 protocol, mostly
• Some fixes to wlr-screencopy, like picking the wrong drm device on multi gpu
• Adds support for connector names in output_name

Thanks! It seems the PR was not based on an updated version of master. Could you rebase it?

[Dregu]

Yeah sure next week, I just pushed it as a placeholder.

I hate submodules.

It looks like this PR has been idle for 90 days. If it's still something you're working on or would like to pursue, please leave a comment or update your branch. Otherwise, we'll be closing this PR in 10 days to reduce our backlog. Thanks!

Oh hi bot, had a nice summer? I honestly have not followed or used sunshine for 90 days, but I'm kinda still invested in rebasing this and getting it over with. I'll try to remember to do something in the next few weeks. wlr-screencopy has been deprecated for 2 years anyway and should die.

Rebased. There are only minor changes since Feb, like letting gbm pick the modifiers. May have somehow degraded the fixes that were made to the old screencopy proto while I was out, but it's not even supposed to be used.
