Speaker sample various updates

[kul3r4]

• Uses Media Toolkit, Exoplayer and opens a separate screen for Player
• Adds navigation to Player and Volume Screen
• Uses Wear Compose progress ring
• Removes animation

Still need removing Constraint Layout, addressing in future PR.

New version SpeakerSamplenew.webm

Old version speakersampleapp.webm

Looks great, but mixing activity and view model is a code smell.

Thanks! PTAL I removed the context from the viewModel
