Change x11/xorgproto to become a build dep

Change x11/xorgproto to become a build time dependency when added to
USE_XORG.  Change the dependency to be on the port, rather than a file the
port installs.
Fix fallout.
Bump portrevision on depending ports.

Switch to xorgproto instead of individual packages

Upstream used to distribute protocol headers as separate packages, but has
decided to merge those to a common package, named xorgproto.  This update
tracks that change.

* Add a new port, x11/xorgproto, with are protocol headers for xorg.
* Hook the new protocol port to the build and to infrastructure in
  bsd.xorg.mk.
* Update all ports with a dependency on any of the old *proto packages to
  instead depend on xorgproto.  Bump portrevision.
* Delete the old *proto packages, update MOVED.
