Improve DGEMM performance for smaller sizes. AOCL DYNAMIC is incorporated at blas interface to enable
calling bli_dgemm_small when optimum number of threads implied is 1 for (n and k < 10).
Improved smart threading logic for dgemm,
Additional conditions at the blas interface added to invoke bli_dgemm_small.
Removed N > 3 condition from bli_dgemm_small.
