c4b9bd3788 Add full FD order support (2nd/4th/6th/8th) to C derivative kernels via ghost_width dispatch
Wrap each C kernel in #if (ghost_width == N) blocks matching Fortran stencil
coefficients from diff_new.f90, kodiss.f90, and lopsidediff.f90. Add fast-path
indexing for ord=1,4,5 in share_func.h.
