Add -auxfromfile option for reading an auxiliary matrix from file, which is then used to build the preconditioner. This is useful, for example, for the case when a filtered version of A is used to build the preconditioner.
Further unification of GPU implementation across cuda/hip/sycl.
Implements the parallel matrix matrix product in sycl.
HYPRE_CUDA_LAUNCH and HYPRE_SYCL_LAUNCH macros have
been unified under HYPRE_GPU_LAUNCH for kernel launches.
Replace HYPRE_SetSpGemmUseCusparse with HYPRE_SetSpGemmUseVendor.
* Added new capabilities to allow multilevel assignment of solver options
* New (local) block Jacobi option for smoothers and intergrid operators
* Added capabilities to do CPR in MGR
* Updated non-Galerkin strategy for constructing the coarse grid.

This PR fixes a segmentation fault on HYPRE_SStructGraphDestroy. The error occurred when the number of graph entries added to the SStructGraph via HYPRE_SStructGraphAddEntries was larger than 1000.
This PR fixes compilation of the "complex" build variant of hypre. It also adds hypre_csqrt for computing the square root of an HYPRE_Complex number. This function/macro works when enable-complex is turned on/off.
Thir PR adds a factorized sparse approximate inverse (FSAI) implementation on hypre, which can be used as a standalone solver, preconditioner to Krylov methods, or complex smoother to BoomerAMG. Particularly, we consider the adaptive algorithm version, where the sparsity pattern of the lower triangular factor G is built dynamically, i.e., during an iterative procedure that tries to find the best nonzero positions for a given row of G. This implementation was performed on top of the IJ interface. It uses the diagonal portion of A for constructing G, i.e., it's a block-Jacobi method in the MPI sense. List of additional changes:
* Add caliper instrumentation to FSAI.
* Add ZeroGuess option to FSAI.
* Performance optimizations.
* Add OpenMP support to FSAI.
* Make internal BLAS/LAPACK functions thread-safe.
* Update CMake build.
* Add new test cases: beam_tet_dof459_np1, beam_hex_dof459_np2, and beam_tet_dof2475_np4.
* Add documentation for FSAI.
