Optimize svg assets

[RiedleroD]

I wanted to finish optimizing all of them before opening the PR but I think that's not happening anymore. As far as I can see, none of those SVGs are actually directly used inside the app. Otherwise, this would probably be a significant performance improvement. So this PR really only saves about 60KiB when downloading the repo and not much else. Maybe next time someone wants to change some of those icons it'll be easier because they're less messy. idk.

I'll probably optimize some of the worse xml files that actually get used some other time and open another PR.

What is it?

• [ ] Bugfix (user facing)
• [ ] Feature (user facing)
• [ ] Codebase improvement (dev facing)
• [x] Meta improvement to the project (dev facing)

The APK can be found by going to the "Checks" tab below the title. On the left pane, click on "CI", scroll down to "artifacts" and click "app" to download the zip file which contains the debug APK of this PR.

The github preview shows that all optimized svgs now have a size of 0x0px, e.g.:

I feel like this might lead to problems if some code implicitly depends on these default height/widths?
