ada: Deconstruct C header for the SCOs unit

The C version of SCOs unit provided a gigi interface to source code obligations
that at some point were generated by the frontend. This functionality has been
deconstructed long ago.

gcc/ada/ChangeLog:

	* libgnat/g-dyntab.ads (Instance): Update and extend comment.
	* scos.ads: Remove comment about the corresponding C header.
	* scos.h: Remove.
