x86/cpu/intel: Fix the MOVSL alignment preference for extended Families
The alignment preference for 32-bit MOVSL based bulk memory move has
been 8-byte for a long time. However this preference is only set for
Family 6 and 15 processors.
Use the same preference for upcoming Family numbers 18 and 19. Also, use
a simpler VFM based check instead of switching based on Family numbers.
Refresh the comment to reflect the new check.
