Identify if the device is a Speaker, Television or a Receiver

[felipecrs]

In order to properly classify and render the Media Player in Home Assistant, it would be great if the library could expose whether the device is a real television or just rather a receiver.

Some examples:

• Sony Android TV -> Television
• Xiaomi Mi Box -> Receiver (set top box)
• Nest Hub -> Television (smart display)
• Chromecast -> Receiver
• Nest Mini -> Speaker
• Chromecast Audio -> Speaker (considering that there isn't an "Audio Receiver" class)

Speaker devices can already be classified with the current tooling:

• How to programmatically tell if a device is a speaker? #632
• Set Google Cast audio devices as speakers home-assistant/core#73832

But there isn't a way (which I found) to determine whether it's a television or not.
