Add a new function CCTK_MaxGFDim to the flesh which returns the

(maximum) dimension of all grid functions.

Cactus can currently not handle the case where one uses grid arrays of
dimension D while grid functions have a dimension less than D.  During
initialisation, Cactus sets cctk_dim to the largest dimension of all
grid variables in all active thorns.  This is arguably wrong; cctk_dim
should be set to the (maximum) dimension of the grid functions.

This patch adds a new function CCTK_MaxGFDim to the flesh which
returns the (maximum) dimension of all grid functions.  This function
is used to set cctk_dim.
