Reserve space for result in ::FilterContents
This changes the implementation for the specific bug listed and
proactively fixes it in the other overrides. The general bug here is
that if you concat a WideString in a tight loop without first
reserving space, each call will cause an allocation size change and
memcpy. This is very expensive and causes ClusterFuzz cases to
timeout.
