x86: Add NT_X86_SHSTK note
Define NT_X86_SHSTK which is the note for x86 Shadow Stack (SHSTK) to
support Intel SHSTK in Linux kernel.
For now only userspace shadow stack and kernel IBT are supported by the
linux kernel. This note should be used instead of NT_X86_CET introduced
in the commit "x86: Add NT_X86_CET note", as it is outdated and only
used by old binutils versions.
