Prior to this change, the number of accumulations passed into calculate_rtol_atol was 1. That said, in most cases, this is not correct when there are multiple workgroups contributing to the same macro tile in C. This change ensures uses the function estimate_num_wgs_per_tile, which was extracted into a common file and generalized, to estimate the number of workgroups per macro tile. This estimate is passed into calculate_rtol_atol to ensure we get a better relative and absolute tolerance.
