Auto merge of #86034 - nagisa:nagisa/rt-soundness, r=m-ou-se

Change entry point to 🛡️ against 💥 💥-payloads

Guard against panic payloads panicking within entrypoints, where it is
UB to do so.

Note that there are a number of tradeoffs to consider. For instance, I
considered guarding against accidental panics inside the `rt::init` and
`rt::cleanup` code as well, as it is not all that obvious these may not
panic, but doing so would mean that we initialize certain thread-local
slots unconditionally, which has its own problems.

Fixes #86030
r? `@m-ou-se`
