test(cloudflare): Increasing timeout and exit with reason

[JPeer264]

Hope to have a better reasoning on #21544 and re-enabling two skipped tests.

With that PR there are two things happening

1. the timeout increases as I couldn't think of anything else other than the worker is not fast enough to spin up.
2. When something crashes for some reason it fails fast rather than waiting for the timeout to be over, including a better error description with the code and the signal. Maybe then the reasoning is better of what is actually happening (in case it fails before)
