Hypre IJ interface: Enable access to additional solvers and preconditioners available in Hypre

[sayerhs]

This PR extends the AMReX hypre IJ interface to allow access to additional solvers and preconditioners available in hypre.

• Refactored HypreABecLap3 and HypreNodeLap (IJ matrix/vector ParCSR interfaces) and created a new IJ interface class that provides a unified way to access Hypre ParCSR solvers.
• In addition to BoomerAMG, adds support for 7 other ParCSR solvers (GMRES (4 variants), PCG, BiCGSTAB, and Hybrid). Also adds support for BoomerAMG and Euclid as preconditioners for solvers that can use a preconditioner.
• Adds support to parse user options to configure hypre library via AMReX ParmParse interface and input file, using a custom namespace (default is hypre)
• Adds MLMG::setHypreOptionsNamespace that allow applications to customize the namespace for different types of linear solvers (e.g., mac_proj.hypre.<option>, nodal_proj.hypre.<option>, etc.)
• Add option to skip solver/preconditioner setup step recompute_preconditioner for cases where the matrix coefficients do not change.
• Add option to dump linear system in hypre IJ{Matrix,Vector} format for debugging.

Additional background

The extensions to hypre interface supports ExaWind AMR-Wind overset and RANS applications.
