<sys/platform/x86.h>: Add Intel Key Locker support
Add Intel Key Locker: https://software.intel.com/content/www/us/en/develop/download/intel-key-locker-specification.html support to <sys/platform/x86.h>. Intel Key Locker has 1. KL: AES Key Locker instructions. 2. WIDE_KL: AES wide Key Locker instructions. 3. AESKLE: AES Key Locker instructions are enabled by OS. Applications should use if (CPU_FEATURE_USABLE (KL)) and if (CPU_FEATURE_USABLE (WIDE_KL)) to check if AES Key Locker instructions and AES wide Key Locker instructions are usable.
