Notify when a NPC Facehugger facehugs someone (#3884)

# About the pull request

NPC facehuggers now also send out a notifcation like player facehuggers
do when they facehug someone.

# Explain why it's good for the game

With player huggers able to do this, it makes sense for regular huggers
to do the same to notify the hive of a new infection (though eggs,
morpher, or even traps), giving the Xenos valuable information. This
also gives feedback for Carriers when their trap facehugs someone.
