rocBLAS 4.2.0 for ROCm 6.2.0

Additions

• Level 2 functions and level 3 trsm have additional ILP64 API for both C and FORTRAN (_64 name suffix) with int64_t function arguments
• Cache flush timing for gemm_batched_ex, gemm_strided_batched_ex, axpy
• Benchmark class for common timing code
• An environment variable "ROCBLAS_DEFAULT_ATOMICS_MODE" to set default atomics mode during creation of 'rocblas_handle'
• Extended dot_ex to support single-precision (fp32_r) input and double-precision (fp64_r) output and compute types

Optimizations

• Improved performance of Level 1 dot_batched and dot_strided_batched for all precisions. Performance enhanced by 6 times for bigger problem sizes measured on MI210 GPU

Changes

• Linux AOCL dependency updated to release 4.2 gcc build
• Windows vcpkg dependencies updated to release 2024.02.14
• Increased default device workspace from 32 to 128 MiB for architecture gfx9xx with xx >= 40

Deprecations

• rocblas_gemm_ex3, gemm_batched_ex3 and gemm_strided_batched_ex3 are deprecated and will be removed in the next major release of rocBLAS. Please refer to hipBLASLt for future 8 bit float usage https://github.com/ROCm/hipBLASLt
