src, child_process: fix fatal error on Array prototype pollution

[Soumyadeep765]

Add an object check in ParseStdioOptions to prevent V8 from crashing with "v8::ToLocalChecked Empty MaybeLocal" when Array.prototype has been polluted. This replaces the fatal error with a controlled JavaScript TypeError (ERR_INVALID_ARG_TYPE).
