Revision of D102858. Raise dlwrap arity argument to template argument
so the correct value is given in the error message. E.g. '2 == 1' instead of
'2 == trait<>::nargs'.
Arity higher than it should be:
Before diff
```
$/plugins/cuda/dynamic_cuda/cuda.cpp:23:1: error:
static_assert failed due to requirement '2 == trait<cudaError_enum (*)(unsigned int)>::nargs'
"Arity Error"
DLWRAP_INTERNAL(cuInit, 2);
^~~~~~~~~~~~~~~~~~~~~~~~~~
...
$/include/dlwrap.h:166:3: note: expanded from macro
'DLWRAP_COMMON'
static_assert(ARITY == trait<decltype(&SYMBOL)>::nargs, "Arity Error"); \
```
