Bob Nystrom b1e8d3f81e feat: add foreign method interface with native call support and argument passing ...

Introduce the `WrenNativeMethodFn` callback type and `METHOD_FOREIGN` enum value to allow host applications to define C-implemented methods on Wren classes. Add `wrenDefineMethod`, `wrenGetArgumentDouble`, and `wrenReturnDouble` API functions, along with `nativeCallSlot` and `nativeCallNumArgs` VM fields to manage foreign call state. Implement `callForeign` in the interpreter loop to invoke native methods and handle stack cleanup. Move `MAX_PARAMETERS`, `MAX_METHOD_NAME`, and `MAX_METHOD_SIGNATURE` constants from `wren_compiler.c` to `wren_common.h` for shared use across the VM.
