Add OpenMP parallelization to BSSN RHS hot-path stencil routines

Enable OpenMP threading for the dominant computational kernels:
- makefile.inc: add -qopenmp to f90appflags
- diff_new.f90: split fderivs/fdderivs into OpenMP interior + serial boundary
- kodiss.f90: split kodis into OpenMP interior + serial boundary
- lopsidediff.f90: add OMP PARALLEL DO COLLAPSE(2) to lopsided
- fmisc.f90: parallelize symmetry_bd bulk array copy
- bssn_rhs.f90: add OMP WORKSHARE to array-syntax operations

-    Calculate 3D Vector RMS and component-wise RMS (X, Y, Z) independently.

-    Uses r = sqrt(x^2 + y^2) as the denominator for all error normalizations.

+    This function computes the RMS error independently for BH1 and BH2 trajectories,
