[cr136] Fix print_rust_log override args using cxx now

This is a simple change to the function signature itself to once again
be matching with the one in the override. The type changes are pretty
much analogous to what was there before.

    Use cxx for FFI between Rust and C++ logging code

    Instead of bindgen, use cxx to generate binding for the C++
    print_rust_log fn called from Rust. This will make it possible to use
    cxx types such as rust::Str.

    Bindgen is still used to generate LogSeverity bindings, since that is
    the only way to have non-opaque bindings while keeping C++ as the
    source of truth.
