feat(ext/ffi): Callbacks (#14663) This commit adds support for unstable FFI callbacks. A callback is registered using the `Deno.UnsafeCallback` API. The backing memory for the callback can be disposed of using `Deno.UnsafeCallback#close`. It is not safe to pass the callback after calling close. Callbacks from other than the isolate thread are not supported. Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com> Co-authored-by: Bert Belder <bertbelder@gmail.com>
