For the Fuchsia platform we build libstd with panic=abort and would like a way to run tests with that enabled. This adds low-level support for this directly to compiletest.

In the future I'd like to add high-level support in rustbuild, e.g. having target-specific flags that allow configuring a panic strategy. (Side note: It would be nice if we could also build multiple configurations for the same target, but I'm getting ahead of myself.)

This plus #84500 have everything that's needed to get ui tests passing on fuchsia targets.

Part of #84766. Note that this change only includes the header on tests which need an unwinder to build, not those which need it to run.
