LOG: [X86] Add detection for more Tremont models (#67150)

Fix the issue that only the server series Tremont processors (Snow Ridge
& Elkhart Lake) can be detected as Tremont, while the client series
(Jasper Lake & Lakefield) will be guessed as Goldmont.

Noted that Lakefield is missing some features compare to other Tremont
processors, but those features are also missing on `FeatureTremont`,
which shouldn't be a problem. Those features are `waitpkg`, `movdiri`
and `movdir64b`.
