avoid using uninitialised variables in CALC_ANGLES
(with #define W2_FILL_NULL_REGIONS, was stopping with open64+trapuv on ACES)

add the computation of the cos/sin(angle between model north and
geographical north). I put the new routine into
rotate_spherical_polar_grid.F, and so far the only place where it is
called is from ini_spherical_polar_grid.F. But I guess it could also
be called elsewhere (whenever AngleCosN and AngleSinN are not read or
incorrect[=0]).

 add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
 usingSphericalGrid, this allows to define the rotated grid coordinates
 via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
 geographical coordinates according to the inverse of the rotation defined
 by the Euler angles, so that Coriolis parameter and online-interpolation by
 exf works with the geographical coordinates on XC/YC/XG/YG.

 The three Euler angles PhiEuler, ThetaEuler, and PsiEuler
 define the rotation about the original z-axis (of an sphere
 centered cartesian grid), the new x-axis, and the new z-axis,
 respectively.
 Naturally, this feature does not work with all packages, so the
 some combinations are prohibited in config_summary (flt,
 flt_zonal, ecco, profiles), because there the coordinates are
 assumed to be regular spherical grid coordinates.
