fix(repl): don't hang on unpaired braces (#8151)

Previously, entering a single ']' would cause repl to forever accepting
new lines, due to that `ValidationResult::Invalid` would actually be
consumed by the editor itself while continue building the lines. Instead
we should mark it as `Valid` and send the bad input for evaluation to
get the proper error from V8.

Before:
```
> ]
(you can keep entering new line here, and it will never consume input
until you Ctrl-C)
```

After:
```
> ]
Uncaught SyntaxError: Unexpected token ']'
>
```
