Talk about assigning, rather than generating, new MultiXactIds.

The word "assign" is used in various places internally to describe what
GetNewMultiXactId does, but the user-facing messages have previously
said "generate". For consistency, standardize on "assign," which seems
(at least to me) to be slightly clearer.
