Merge branch 'hongzh/sell-hip' into 'main'

Add SELLHIP

See merge request petsc/petsc!7338

Convert to MATSELL or its subclass when calling MatSetType()

This simplifies user code so that users do not need to convert the matrix themselves.

Add a warm-up operation for the benchmark driver

- HIP uses a lazy initialization for GPUs, so the first call takes extra time
- The warm-up operation is excluded from logging

Add SELLHIP

- The HIP kernels are converted directly from their CUDA version
- AMD GPUs and NVIDIA GPUs use different warp sizes. We set the warp size to 64 by default for AMD GPUs to faciliate comp
