  1. Open Boundary Poisson Solver 

    This adds an open boundary Poisson solver based on the James's algorithm.
To use it, the user builds an amrex:OpenBCSolver object, which can be reused
until the grids change, and then call OpenBCSolver::solver.

Currently, this is for 3D cell-centered data only. The solver works on CPU,
Nvidia GPUS, and AMD GPUs.  The SYCL version of a couple of kernels for
Intel GPUs are to be implemented.
