Rollup merge of #69969 - iximeow:sigstack-guard-page, r=cuviper
unix: Set a guard page at the end of signal stacks This mitigates possible issues when signal stacks overflow, which could manifest as segfaults or in unlucky circumstances possible clobbering of other memory values as stack overflows tend to enable. I went ahead and made a PR for this because it's a pretty small change, though if I should open an issue/RFC for this and discuss there first I'll happily do so. I've also added some example programs that demonstrate the uncomfortably clobber-happy behavior we currently have, and the segfaults that could/should result instead, [here](https://github.com/iximeow/jubilant-train).
