x86-64: Enable Intel CET

Intel Control-flow Enforcement Technology (CET):

https://en.wikipedia.org/wiki/Control-flow_integrity#Intel_Control-flow_Enforcement_Technology

requires that on Linux, all linker input files are marked as CET enabled
in .note.gnu.property section.  For high-level language source codes,
.note.gnu.property section is added by compiler with the -fcf-protection
option.  For assembly sources, include <cet.h> to add .note.gnu.property
section.
