Auto merge of #116037 - wesleywiser:stack_protector_test_windows, r=cuviper
Add `-Zstack-protector` test for Windows targets
Add variants of the `stack-protector-heuristics-effect.rs` test for 32-bit and 64-bit MSVC Windows and update the original test to run on GNU Windows targets.
I added two tests instead of trying to modify the original because:
- MSVC uses a different function name (`__security_check_cookie` to perform the test rather than doing the test inline and calling `__stack_chk_fail`).
- LLVM's stack protection pass doesn't currently support generating checks for [frames with funclet based EH personality](https://github.com/llvm/llvm-project/blob/37fd3c96b917096d8a550038f6e61cdf0fc4174f/llvm/lib/CodeGen/StackProtector.cpp#L103C1-L109C4).
- 32-bit Windows uses classic EH while 64-bit Windows uses table-based EH which results in slightly different codegen.
[CI run with test passing on {i686,x86_64}-{msvc,mingw}](https://github.com/rust-lang/rust/actions/runs/6275450644/job/17042958375?pr=116037)
