Followup to #36739 (and currently built atop it), this restores the `pointer(::SubArray{<:Any,<:Any,<:Array,<:Tuple{Vararg{RangeIndex}}}, ::Tuple)` method that was removed in #36405. It does so, however, as a deprecated method, with the actual method being implemented on `(::SubArray{...}, ::CartesianIndex)`.

The rationale here is because the `::Tuple` method was undocumented and only supported on that one _highly_ specific `SubArray` type. I am keeping this patch as minimal as possible for backporting; in the future I aim to support `Vararg{CartesianIndex, Integer}` locations to make this more `getindex`-y and move farther away from the conflation with memory offsets.
