When console.log is called for the first time it initializes
TTYWrap object. However, if there is not enough space on the
V8 stack, creating function template fails and triggers
empty maybe local exception.

Fixes #26829

BTW, Environment::SetMethod() and Environment::SetMethodNoSideEffect() also does ToLocalChecked() on the maybe returned by FunctionTemplate::GetFunction() and also does FromJust() on the Maybe returned by Object::Set(), I wonder why this only crashes in the non-heplers here.

CI: https://ci.nodejs.org/job/node-test-pull-request/21822/ (though it's rather flaky now)

CI was failing due to flaky test-worker-prof and the last run timed out for some reason. The failure seems unrelated to this PR.
