Add ContainsAny{Except} path to SearchValues

[MihaZupan]

Followup after #87621 to add dedicated ContainsAny{Except} paths for SearchValues.
This PR adds such logic for SearchValues that go through IndexOfAnyAsciiSearcher.

I tried to avoid code duplication between IndexOfAny and ContainsAny by abusing generics some more. Don't know if that could lead to any downsides.

#96588 is renaming some files so if/after that is merged, we can wire up ContainsAny{Except} for single-value SearchValues to call into Contains helpers as well.
