Adds support for tracing mmaps in native code and logging that. Notably does not let us call libc::mmap(..) on the Rust side and then munmap it on the native side / the other way; I have ideas for maybe doing that, but they'd be quite a bit more involved since it requires us doing some syscall shimming.

I saw the PR and it's in my queue, but it's a big one so it may take a bit until I have time to dig into this -- sorry.
