@mstankov-amd gfx115x does not seem supported in hipBLASLt CC. @jagadish-amd

hipBLASLt support for gfx1150/gfx1151 has been added since ROCm 6.4.1: https://github.com/ROCm/hipBLASLt/blob/release/rocm-rel-6.4/tensilelite/Tensile/Source/lib/include/Tensile/AMDGPU.hpp#L74

you're right @slojosic-amd, it is supported (according to great help from @jagadish-amd who figured it out, it is enabled in 6.4.2). Given this PR also updates the preferred backend, have you benchmarked hipBLASLt versus rocBLAS for perf?

probably needs ROCm 6.4.2 condition,

(reference ROCm/hipBLASLt#2067)
