Finn Plummer af9f6d61b5 [NFC][VectorUtils] Simplify description of TriviallyScalaraziable intrinsics (#192505)
This pr allows us to specify if an intrinsic is `TriviallyScalarizable`
by specifying it in a more idiomatic way as an intrinsic property.

This was suggested here:
https://github.com/llvm/llvm-project/issues/120169#issuecomment-3805670982,
and would allow for the attached issue to be resolved in a similar
manner by having a `TriviallyVectorizable` property as well.
