bug(parser): infinite loop in tsx

[Boshen]

This is caught by the fuzzer https://github.com/Boshen/oxc/actions/runs/4395420223/jobs/7697210796

To replicate:

Create a test.tsx with the following string:

1<(V=82<<t-j0<(V=$<LBI<(V=ut<I<(V=$<LBI<(V=uIV=82<<t-j0<(V=$<LBI<(V=ut<I<(V=$<LBI<(V<II>

run cargo run -p oxc_parser --example parser -- test.tsx

and it will run forever.

I'm gussing this is the result of parsing the ambiguous < token, where TypeScript needs to lookahead and rewind forever.

As a pointer, I suspect ParserState::not_parenthesized_arrow didn't catch a case here.

<( this is the start of parenthesized arrow function, so it kept going and rewinded in an infinite loop.

I pin pointed to the loop and this try_parse rewind:

But I got stuck to find a solution ... everything is intertwined together like a hairball 😢

I give up, I'll copy TypeScript's source code ...
