Bias and more metadata in gradlib and tuned gemm

[gshtras]

Using hipblaslt solutions with bias support for gemms with bias. Comparing them against rocblas with separate bias add for fair comparison.

Writing bias, in dtype, out dtype in the untuned and tuned file to reuse the same tuned csv.
dtypes can be overriden by the command line to tune for fp8

I recall for fp16 gemm, rocblas solutions are also queried. Does this PR make the change for rocblas part of gradlib?

Only so that if a gemm is tuned with bias, times for rocblas are computed while adding bias separately.
All the rest rocblas remains the same, for gemms without bias it is often faster.
