Intent/Message to Send Text To Be Displayed By Device

[pyu-cmcsa]

https://ccp.sys.comcast.net/browse/FIRE-306

API to replace $badger's showToaster method, and support VREX's need to display a voice readout/readback.

Method will take a string of text and pass it to the device/aggregated experience, such that the device/experience can then display the text as though it were originated by the device/experience.

Usecases:

• at app open, a message reminding customers that they are opening a 3rd party app/using metered interenet
• at app deeplink, a message informing customers to return to the aggregated experience press a specific remtoe button
• after voice utterace, a message informing customers what the Speech-to-text translation readout was interpreted as

These should not be treated as "notifications" but this is a transactional message.

Scope can be reduced to just being an intent for VREX purposes so that Firebolt is not responsible for executing the display of the messaging and only passing the intent to the application that is responsible for displaying the message.
