Refactor externref related APIs of reference types feature (#971)
Currently when calling wasm_runtime_call_wasm() to invoke wasm function with externref type argument from runtime embedder, developer needs to use wasm_externref_obj2ref() to convert externref obj into an internal ref index firstly, which is not convenient to developer. To align with GC feature in which all the references passed to wasm_runtime_call_wasm() can be object pointers directly, we change the interface of wasm_runtime_call_wasm() to allow to pass object pointer directly for the externref argument, and refactor the related codes, update the related samples and the document.
