Fix iOS build

[domenukk]

iOS was broken both at compile time (i8 != ui pointers) and link time (missing dependencies). This PR fixes that and also adds CI.

Giving up to add Android to CI, it doesn't find the time.h header (same error as #34):

/Users/runner/work/frida-rust/frida-rust/target/aarch64-linux-android/debug/build/frida-sys-15ad3d6ad5fda1d0/out/frida-core.h:8763:10: fatal error: 'time.h' file not found

@domenukk,

I have determined that some versions of NDK and Rust are incompatible. For example, such versions are non-working:

• rust 1.70, NDK 25, clang*
• rust 1.70, NDK 22, clang*
• rust 1.70, NDK 21, clang*
• rust 1.67, NDK 25, clang*

Try these versions: rust 1.67, NDK 22, clang30. This worked for me when I was building LibAFL.

Didn't mean to close :) PR should be ready. I'll not do Android CI for now, it's too much trial and error

@meme would appreciate a merge and release whenever it's convenient, then we can update LibAFL too, thx :)

[domenukk]

Thanks! :)

[domenukk]

Could you make a release plz? :)
