feat(react-router/server-runtime): treat cookie signatures with invalid encodings as invalid

[rossipedia]

• Closes Invalid characters in cookie signature throws a DOMException #13846

When calling atob(), a InvalidCharacterError DOMException is thrown if a character is encountered that is not allowed in Base64 encoding. When that happens, unsign() should just treat the signature as invalid instead of bubbling up that error
