[ ] Needs better platform integration (file management and settings)
[ ] Must not break other platforms
[x] Fix caching of emsdk libraries in the GH build
[x] On Firefox on Android, the screen is drawn too large. I suppose the condition for iOS in qtframebuffer.cpp needs to be extended

[ ] Fix caching of emsdk libraries in the GH build

Apparently that's because setup-emsdk behaves differently if the cache was found. If it's not found, it'll install emsdk into emsdk-main and create a cache in emsdk-cache. The system libs end up in emsdk-main in those builds, but only emsdk-cache is cached. If the cache is found, it uses emsdk-cache as emsdk location and build system libs inside that directory.

Fix caching of emsdk libraries in the GH build

Fixed by running emsdk manually instead of using the setup-emsdk action

-O3 -flto is not noticably faster compared to the default (-O3 for object files, -O2 for linking), but it takes twice as long to build.
