Sets a function to clear an element of array.
The clear_func will be called when an element in the array
data segment is removed and when the array is freed and data
segment is deallocated as well.
Note that in contrast with other uses of GDestroyNotify
functions, clear_func is expected to clear the contents of
the array element it is given, but not free the element itself.
Since 2.32
