I added Batch rendering because I don't know

[carabistouflette]

Hey guys,
I made a fork of Hyprland with batch rendering to reduce the number of draw calls. If you guys want to check this out the link is:
https://github.com/carabistouflette/Hyprland (on the branch feat/render-batching)

I made it with TDD methodology so it should not be too much bugged but we never know what can happen so please try it out exhaustively before any merge.
The fork is updated as of now (last commit is 8ebff19).

I also made some documentation so you can understand what i've done (in docs/RENDER_BATCHING.md). At the end of the doc is what i'm planning to add later.

Should I start the pull request now or should I wait for more features?

The doc is half made with ChatGPT as I don't really like making them. It should be Ok (as I double checked it) but there are obvious AI things like the performance benefits part. Don't hesitate to ask me for improvements about it.

you probably want to make a PR as early as possible to make it easier to review and merge. and discuss on code bits etc
