[Release/2.4] Remove amax_ptr from scaled_gemm for UT test_scaled_mm_vs_emulated_*float*_cuda and Updating unit test case based on removing amax from _scaled_mm

[amd-sriram]

Fixes https://github.com/ROCm/frameworks-internal/issues/8493 and https://github.com/ROCm/frameworks-internal/issues/10198

cherry pick commit - 39a6179

amax was removed from _scaled_mm by pytorch#128683. Remove it from the internal at::cuda::blas::scaled_gemm, as well. This allows hipBLASLt to find additional solutions rather than forcing amax to be used and then discarding the result.

Also removing amax comparison in the unit test.
