Use fallback engine for as the non-temporal engine for unknown CPU types
Using the non-temporal AVX engine for unknown CPU types looks like a mistake to me, and the default built into the switch case is to use the fallback engine. I don't think this is causing issues now, but it might once we add ARM support. PiperOrigin-RevId: 561097994 Change-Id: I7f0edd447017c09acd49e4ea11476e32740d630a
