[ROCm] Enable a few bfloat16 unit tests (#105177)
Currently a few unit tests from **test_matmul_cuda** and **test_sparse_csr** test suites are being skipped on ROCm.
This PR is to enable the following unit tests on ROCm (~30 UTs):
test_cublas_baddbmm_large_input_* (__main__.TestMatmulCudaCUDA)
test_addmm_sizes_all_sparse_csr* (__main__.TestSparseCSRCUDA) when m==0 or n==0 or k==0
