- We add a new path for supporting universal builds without #embed . `xxd` causes the compiler to run out of memory, so instead we embed it as a string literal created at compile time.
- This file is created in `net.sh`, and only if `--embed-dir` isn't supported + we are doing a universal build.
- This was necessary because Android NDK seems to not support embed, idk why
- A couple other Makefile tweaks were necessary for the Android path.
- While we're at it, remove the non-universal arm64 windows and android binaries.
