Followup to https://github.com/JuliaLang/julia/pull/31724/files#r317686891; instead of widening the index type dynamically based upon the index vector length, just throw an error in the case where the index type cannot hold all the indices in a CSC format. This previously was an OOB access (and likely segfault) in 1.2, so throwing an error here is not a breaking change -- and throwing an error restores type stability, addressing the performance regression flagged in #32985.
