Replace flat allocatable arrays x_cb/y_cb/z_cb, x_cc/y_cc/z_cc,
and dx/dy/dz with a derived type having .cb, .cc, and .spacing
components. All three executables (pre_process, simulation,
post_process) updated across 47 files.
Key design decisions:
- pre_process keeps scalar dx/dy/dz as minimum cell-width scalars;
only x_cb and x_cc are folded into x%cb and x%cc
- OpenMP GPU target uses whole-struct declare target (x, y, z) since
component-level declare target is invalid; OpenACC uses component-level
- 2dHardcodedIC.fpp wraps dx*dy in #ifdef MFC_PRE_PROCESS for the
scalar vs per-cell context difference
Special variable collisions fixed:
- m_chemistry.fpp: local integer x/y/z -> cx/cy/cz
- m_weno.fpp: local real y(1:4) scratch -> ys
- m_viscous.fpp: local real dx(1:3) scratch -> ds
- m_ibm.fpp: local scalar dx/dy/dz -> dx_loc/dy_loc/dz_loc
- m_cbc.fpp: Fypp template d${XYZ}$ -> ${XYZ}$%spacing
Implements items 7 and 5 from issue #1427: - x_a/x_b/y_a/y_b/z_a/z_b -> type(bounds_info) :: x_stretch, y_stretch, z_stretch - bf_x/bf_y/bf_z + k_x/w_x/p_x/g_x (and y/z) -> type(body_force_axis) :: bf_x, bf_y, bf_z

Remove module-level dx, dy, dz scalars from pre_process m_global_parameters. Add min_spacing field to the grid_axis derived type so each axis carries its own minimum cell width. Update all call sites in m_grid, m_start_up, m_icpp_patches, m_mpi_common, and 2dHardcodedIC.
After reading grid data from files, compute and store min_spacing on each axis in both serial and parallel paths. Matches the pre_process pattern so min_spacing is consistent across all three executables.
Group the three directional boundary condition variables (bc_x, bc_y, bc_z of type bc_dir_t) into a single bc_xyz_info struct accessed as bc%x, bc%y, bc%z. Updates all Fortran source, Fypp macros, Python toolchain, example cases, and documentation.
