x86/shstk: Enable shadow stacks for x32
1. Add shadow stack support to x32 signal.
2. Use the 64-bit map_shadow_stack syscall for x32.
3. Set up shadow stack for x32.
Add the map_shadow_stack system call to <fixup-asm-unistd.h> and regenerate
arch-syscall.h. Tested on Intel Tiger Lake with CET enabled x32. There
are no regressions with CET enabled x86-64. There are no changes in CET
enabled x86-64 _dl_start_user.
