* Change the return type of run_gemm_combinations in the basic tests * Change the return type of run_gemm_combinations in the universal tests * Add universal GEMM tests for bf16 x pk_i4 and fp16 x pk_i4 * Add universal GEMM test for fp8 x pk_i4 * Add basic GEMM tests for bf16 x pk_i4, fp16 x pk_i4 and fp8 x pk_i4. * Add missing GemmTypeConfig<ck_tile::fp8_t, ck_tile::pk_int4_t, ck_tile::half_t> * Add missing GemmTypeConfig<ck_tile::bf16_t, ck_tile::pk_int4_t, ck_tile::bf16_t> * No need for utility in test_ck_tile_elementwise_1d * Fix conversion from pk_int4x4_t to bf16x8_t in PassThroughPack8 * Avoid union-based type punning in float_to_bf16_truc_raw to make it constexpr compliant * For consistency also make float_to_bf16_truc_nan_raw constexpr compliant by removing the union * Use a static_cast to bfloat16_t only when CK_TILE_USE_LLVM_BUILTIN_BF16 is enforced * Convert from float to bf16 during compilation rather than using magic values * Fix conversion from pk_int4x4_t to fp8x8_t in PassThroughPack8 * Comment out the basic test for fp16 x pk_i4 as it does not pass * Add missing GemmTypeConfig<ck_tile::bf8_t, ck_tile::pk_int4_t, ck_tile::half_t> * Fix conversion from pk_int4x4_t to bf8x8_t in PassThroughPack8 * Add basic and universal GEMM tests for bf8 x pk_i4 * Switch back to amd_assembly_i4_to_fp8x8 in PassThroughPack8 as it works now * Switch back to amd_assembly_i4_to_bf8x8 in PassThroughPack8 as it works now * Remove the inefficient fallbacks for fp8 and bf8 in elementwise/unary_element_wise_operation.hpp * Use explicit macros for enabling and disabling the the constexpr lookup based converters * Fix two failing tests * Avoid union-based type punning in float_to_bf16_rtn_raw to make it constexpr compliant * Use float_to_bf16_rtn_raw instead of float_to_bf16 to create the bf16 lookup table for use in conversions from pk_int4 to bf16 * On ROCm 7.0.1 we need an explicit cast to from uint16_t to bf16_t
