Add component NotificationFrame & CaptureAudio parts for testing (#36081)

Adds component NotificationFrame. It implements a subset of MessageNotification as a Component and refactors MessageNotification to use NotificationFrame. Having some notification UI Component is nice as it allows us to easily build new types of notifications.

Uses the new NotificationFrame component for CaptureAudioNotification. 

Adds a CaptureAudio action in the dev namespace (not meant for
end-users). It records 10 seconds of audio and saves that to a wav file.

Release Notes:
