Optimize gtk_widget_path_copy() by preallocating "elems" array

gtk_widget_path_copy() currently calls g_array_append_val() in a loop,
which is inefficient due to reallocating the array's memory. Calling
g_array_set_size() before entering the loop reduces the number of CPU
cycles used by roughly 30%.
