lavc: Add new header for SEI payload types

These form a common namespace between the H.264, H.265 and H.266
standards, so we can use the same definitions in all three places.

+// SEI payload types form a common namespace between the H.264, H.265
+// and H.266 standards.  A given payload type always has the same
+// meaning, but some names have different payload types in different
+// standards (e.g. scalable-nesting is 30 in H.264 but 133 in H.265).
+// The content of the payload data depends on the standard, though
+// many generic parts have the same interpretation everywhere (such as
+// mastering-display-colour-volume and user-data-unregistered).
