880b9728 - More efficient indices validations for compressed sparse formats. (#81108)

More efficient indices validations for compressed sparse formats. (#81108) As per title. Some of the features: - native kernels both for the CPU and CUDA without device syncs. - If needed, invariant checks 5.1 - 5.5 could be improved to utilize vectorization. This will require implementing a conversion `Vectorized -> bool`. That's a follow-up.
