[refactor/fix] remove extra cpitch in layout_dense
Cummulative pitches were kept up to the total storage size of the layout, even though our code never uses this information. Remove a bug due to bad array size arithmetic, and remove the extra element in the array too. This patch also removes the pitches provided by the user from the struct.
