Instantiate the WASM module from a WasmEdge AST Module and invoke a function by name.

This is the function to invoke a WASM function rapidly. Load and instantiate the WASM module from the WasmEdge AST Module, and then invoke the function by name and parameters. If the Returns buffer length is smaller than the arity of the function, the overflowed return values will be discarded. After calling this function, a new module instance is instantiated, and the old one will be destroyed.

This function is thread-safe.

\param Cxt the WasmEdge_VMContext. \param ASTCxt the WasmEdge AST Module context generated by loader or compiler. \param FuncName the function name WasmEdge_String. \param Params the WasmEdge_Value buffer with the parameter values. \param ParamLen the parameter buffer length. \param [out] Returns the WasmEdge_Value buffer to fill the return values. \param ReturnLen the return buffer length.

\returns WasmEdge_Result. Call WasmEdge_ResultGetMessage for the error message.
