This add a new field_gpu type field implementation for which the rhs
hand side method is implemented using CUDA fortran.
Class field_type is made and abstract class with deferred type
boudn method rhs. Previous (cpu based) field_type becomes
field_cpu_type that inherits form the abstract class. Same goes for
new GPU based field type.
Because statements like
rhs = temp_field%rhs()
lead to a runtime error when compiled with nvfortran, rhs method is
changed to return a real array instead of a class(field_type.
This means the time integration must be slightly changed to use
(field + real) additions (field_add_real added to + operator
for type field_type.
Build is configured via CMake. Which includes CUDA source files
whether or not compiler is nvfortran.
Currently specifying FFLAGS at the command line is still required
for unknown reasons. Setting target_compile_options in the CMake
configuration doesn't seem to do the trick.
