[Fix] (Pipe): the records two families keep of their own are forgotten with the session too

MGPipeForgetAllPublications cleared the publication latch, but two death helpers do not ask the
latch: vertex elements ask the vertex-input emitter's RecordIsPublished and buffers ask the
resource tracker's WasPublished.  A VAO and its buffers destroyed with the GL context after the
split roles were down still found themselves published there, and glmark2's eglTerminate stopped
on the same assertion eglinfo's did (ResolveVertexElements, then ResolveResourceIn for a buffer).

Both records are now dropped beside the latch: the emitter's latches whole, the tracker's
Published flags.
