move usages to use this repo

[zepumph]

There are over a hundred usages to convert. Let's do that here.

[zepumph]

This will also involve:

• [x] adding UTTERANCE_QUEUE to the config path
• [x] moving tests over
• [x] deleting scenery-phet files

[zepumph]

I replaced usages with the regex:

SCENERY_PHET/accessibility/(ActivationUtterance|AlertableDef|Utterance|UtteranceQueueIO|UtteranceTests|ValueChangeUtterance|ariaHerald|utteranceQueue)'

for

UTTERANCE_QUEUE/$1'
