A few more comments -- I think I will approve when these are addressed. There's a lot going on in this PR and I've tried my best to make sense of it, but there's a lot of "patterning" with complex lambdas, boolean template dispatches, etc. I am struggling to find better recommendations but I don't think I can concretely identify what I would prefer in those cases, if anything, at this time.

Are the trailing // necessary if clang-format is already turned off in this section? I'd remove the trailing //.

On some systems, CUDA compiler may have an issue such that it will throw unused variables warnings into your face if you use `if constexpr` with an `else` branch. Such warnings were reported due to a recent merged PR (#10548). This PR rewrites the `else` branch of the `if constexpr` in `lists/contains.cu` into a second `if constexpr` statement with opposite condition to avoid the warnings.

This extends the
lists::containsAPI to support nested types (lists + structs) with arbitrarily nested levels. As such,lists::containswill work with literally any type of input data.In addition, the related implementation has been significantly refactored to facilitate adding new implementation.
Closes #8958.
