gdkarray: Add support for GDK_ARRAY_NO_MEMSET
If all your callers already initialize the array element as needed,
then we don't need to memset it to zero first.
This is pretty useful for the snapshot state stack, because due
to the per-node-type data area the elements on the stack are
quite large, but often a lot of it is not used.
