role-ducking: Add silent sound to the start of a trigger stream if it affects any...

A ducking stream's volume will be decreased before starting original data of the trigger stream.

Here's the condition for the activation of it.
1. When a trigger stream belongs to a group that has fading feature,
2. Any ducking stream of the group is currently running.
3. Adding silent sound will be operated when starting the trigger stream.

[Version] 5.0-91
[Profile] Common
[Issue Type] New feature
