Subject: NEWS.md: Add memory view entry

The memory view interface added at 890bc2cdde is experimental new C-API
set.  This feature permits extension libraries to share a memory area
that contains such a numerical array and a bitmap image.  This is
designed by referring to Python's buffer protocol.
[[Feature #13767]]

 * C API header file `ruby/ruby.h` was split. [[GH-2991]] Should have no impact

+* Memory view interface [EXPERIMENTAL]
+
+  * The memory view interface is a C-API set to exchange a raw memory area,
+    such as a numeric array and a bitmap image, between extension libraries.
+    The extension libraries can share also the metadata of the memory area
+    that consists of the shape, the element format, and so on.
+    Using these kinds of metadata, the extension libraries can share even
+    a multidimensional array appropriately.
+    This feature is designed by referring to Python's buffer protocol.
