Add HIP support for AMD GPUs
...
This commits adds cmake functionality that can
hipify the cuistl framework to support AMD GPUs.
Some tests have been written as HIP does not mirror
CUDA exactly.
CONVERT_CUDA_TO_HIP is the new CMAKE argument.
CMAKE version is increased to include HIP
as a language (3.21 required).
A macro is added to create a layer of indirection
that will make only cuistl files that have been
changed rehipified.
Some BDA stuff is extracted to make sure CUDA
is not accidentally included.

Construct the matrices in the AMG hierarchy (created in the PreconditionerFactory) with deterministic indices if possible.

The function 'setUseFixedOrder' is called if it is defined and the matrices in the AMG hierarchy are constructed with deterministic indices.
If it is not defined yet, it is not called and the matrices in the AMG hierarchy are constructed with non-deterministic indices.

Implement calls to cuBlas, cuSparse and implement necessary
CUDA kernels to perform a single iteration of the jacobi preconditioner.
Add tests that verify new kernels and the preconditioner in its totality.
The preconditioner is verified on 2x2 and 3x3 blocks, which as of now
are the only supported sizes. 1x1 are not supported because cuSparse
does not support it.

i chose to split in a separate _impl file because this code is so
generic that there may be downstream users who want to use on other
matrix types than what we use in opm-simulators.
