Invoke a (local or global) hook that processes elements that get discarded. This
includes elements that are dropped (for malformed sources), but also filtered out
(eg. not passing a {@code filter()} predicate).
<p>
For elements that are buffered or enqueued, but subsequently discarded due to
cancellation or error, see {@link #onDiscardMultiple(Stream, Context)} and
{@link #onDiscardQueueWithClear(Queue, Context, Function)}.

@param element the element that is being discarded
@param context the context in which to look for a local hook
@param <T> the type of the element
