selftests/x86: Add shadow stack test
Add a simple selftest for exercising some shadow stack behavior:
- map_shadow_stack syscall and pivot
- Faulting in shadow stack memory
- Handling shadow stack violations
- GUP of shadow stack memory
- mprotect() of shadow stack memory
- Userfaultfd on shadow stack memory
- 32 bit segmentation
- Guard gap test
- Ptrace test
