Addresses DE-21

23.2.1/11 provides a general no-throw guarantee for erase() container functions, exceptions from this are explicitly mentioned for individual containers. Because of its different name, forward_list's erase_after() function is not ruled by this but should so.

[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]

Proposed resolution:

Add a "Throws: Nothing" clause to both `erase_after` overloads in 23.3.3.4, [forwardlist.modifiers].
