There are exceptionally few 32-bit x86 devices. By removing support for this architecture we can reduce disk usage and "fix" the GH Actions Android workflow. (There aren't a ton of 64-bit x86 devices either, but it's important to support that architecture for those using Android Emulator on Intel dev machines)
