Various Entities make sounds when speaking (#7980)

* Speech Sounds from Goonstation

* Added some speech sound prototypes for humans, mice, and vending machines. More to come later?

* Custom synthesized sound for a vending machine ad

* Gave mice and vending machines Speech Components on their base prototypes to make sounds

* Humans now talk using the 'Alto' voice. In the future this can be changed in customization screen

* New Prototype 'SpeechSounds' with three soundspecifiers for saying sound, asking sound, exclaiming sound.

* SharedSpeechComponent modified from being useless to being responsible for making speech noises.

* Initial creation of SpeechNoiseSystem for making Sounds when certain entities speak.

* whitespace fix

* License fix

* Remove leftover using from debugging

* Added a cooldown editable in yaml

* SharedSpeechComponent has the proper cooldown now. oops
