Debugging stalls on wasm pause evaluator when runtime is paused

[connor4312]

Following a case of #232651

1. Make a Vite react app
2. Set a breakpoint and try to debug
3. Sometimes you get into a stalled state

This seems to be a potential bug(?) or at least a niche behavior in Chromium that prevents (i.e. blocks on) any kind of script execution at instrumentation pauses. Even sending normal REPL-type evaluations at instrumentation pauses don't work. This causes an issue because in some code paths the WebAssembly interception script is first applied during an instrumentation pause. Unfortunately I don't see much of a way around this aside from having a timeout and/or just not awaiting the break application when at an instrumentation pause.

Workaround: Users can work around this either by using js-debug nightly (where this fix is available), or setting "pauseForSourceMap": false in their launch.json. But I think we should take a candidate fix here because it breaks the "hello world" of some common scenarios.
