Add a `WHISPER_CPP_VERSION` static that contains the version number of whisper.cpp that whisper-rs was built with. This can be useful for downstream applications for debugging and logging purposes. This is implemented using [build script metadata](https://doc.rust-lang.org/cargo/reference/build-scripts.html#the-links-manifest-key) for whisper-rs-sys to expose the version number of whisper.cpp defined in `CMakeLists.txt` as metadata to crates that depend on it. Then whisper-rs accesses that build metadata and defines its own internal compile-time environment variable containing the same value, which is then assigned to a static variable. It seemed better to expose this information through build metadata rather than defining a static in whisper-rs-sys directly, despite the extra indirection, so as to keep whisper-rs-sys as pure bindings.
