<sys/platform/x86.h>: Add Intel LAM support
Add Intel Linear Address Masking (LAM) support to <sys/platform/x86.h>. HAS_CPU_FEATURE (LAM) can be used to detect if LAM is enabled in CPU. LAM modifies the checking that is applied to 64-bit linear addresses, allowing software to use of the untranslated address bits for metadata.
