Change Details

Establish a bridge using the `cxx` crate. The definition is in chronik-ffi/src/ffi.rs, see https://cxx.rs/extern-rust.html and https://cxx.rs/extern-c++.html. On the C++ side, we expose `log_println`, which prints a string using `LogPrintf`. In the future we can add more parameters (like file/line no) and use `LogInstance().LogPrintStr`. On the Rust side, we expose `setup_bridge`, which uses `log_println` to print a message. `cxx` generates the files in a fixed location, and we update the CMake list file to add the generated headers and C++ source files. Corrosion builds `chronik-ffi-static`, which we add to the `chronik` target. Corrosion needs the `Rust_CARGO_TARGET` triplet set, see https://doc.rust-lang.org/nightly/rustc/platform-support.html. All the platform targets from `cmake/platforms` are supported, plus `aarch64-apple-darwin` for M1 users. Depends on D11862.

We set the `Rust_CARGO_TARGET` triplet for Corrosion for known targets, see https://doc.rust-lang.org/nightly/rustc/platform-support.html. All the platform targets from `cmake/platforms` are supported, except OSX, which has a known issue with the `cxx` dependency. Depends on D11862.
