Annotate _input_ length of `DCompositionGetStatistics::targetIds` (#1993)

Upstream SAL typo'd this in `_Out_writes_opt_` as `targetCount` instead
of `targetIdCount`.

Note that `actualTargetIdCount` will be set to describe how many target
ids are available or were actually written, whereas `targetIdCount` is
just a maximum number of available items to query in `targetIds`.
