Feature Request: Better Control for Speed in Playback Effects on Android Auto

### What problem does this address?

Speed control on Android Auto isn't ideal. It caps out at x2 and doesn't allow granular control.

### What is your proposed solution?

A slider that encompasses the whole range of speed (.5 - 3) that doesn't require tons of taps.

Additionally, a few preset speeds to toggle between now. That does exist, but only toggles between 1 and 2.

I'd like to set the speeds to quick toggle between and then long pressing or having the option to select from any with a slider.

### Did you search for existing feature suggestions?

- [X] I have searched for existing feature suggestions.

Start by reviewing the Android Auto playback speed controls and the existing behavior that toggles between 1x and 2x. Done means Android Auto supports speed selection across 0.5x–3x, including a slider and configurable quick-toggle presets, without requiring excessive taps.
