Add HIP/ROCm version of matvec function to MatrixHandler class

[pelesh]

As an initial step to porting ReSolve to HIP we might want to start with HIP/ROCm implementation of matvec function. For starters, it would be sufficient to have it running within unit test framework. This work would also require implementing HIP-based linear algebra workspace.

Such development should branch off hip-first-take-dev branch. To build this branch on Frontier one needs to load modules PrgEnv-amd, amd/5.6.0, and cmake. We need our own build of SuiteSparse:

module use -a /lustre/orion/csc359/proj-shared/nkouk/spack-install/modules/linux-sles15-zen3
module load suite-sparse/5.13.0-clang-14.0.0-rocm5.2.0-mixed-ebugiv3

To build use:

git clone git@github.com:ORNL/ReSolve.git
mkdir build && cd build
CC=amdclang CXX=amdclang++ cmake -DRESOLVE_USE_HIP=On ../ReSolve
make

This assumes your build dir is a sibling of the ReSolve source dir.

Note that the hip-first-take-dev branch is under heavy development.
