Default std.posix.system.ucontext_t is void
PR https://github.com/ziglang/zig/pull/20679 ("std.c reorganization")
switched feature-detection code to use "T != void" checks in place of
"@hasDecl". However, the std.posix.system struct is empty, so
compile-time feature detection against symbols in there (specifically
`std.posix.system.ucontext_t` in this case), fail at compile time on
freestanding targets.
This PR adds a void ucontext_t into the std.posix.system default.
This PR also adds pseudo-"freestanding" variation of the StackIterator
"unwind" test. It is sort of hacky (its freestanding, but assumes it can
invoke a Linux exit syscall), but it does detect this problem.
Fixes #20710
