This implements rust-lang/rfcs#3151

Tracking issue: #93203

r? @Amanieu

It now panic!()s on its own, rather than resume_unwind'ing the panic
payload from the thread. Using resume_unwind skips the panic_handler,
meaning that the main thread would never have a panic handler run, which
can get confusing.
