Proposed change

Based on feedback for #147217 I have split my contribution into multiple smaller PRs. This is PR 4/6. PR #147237 should be merged first!

This PR:

Adds select entities for enumTarget settings

Overall changes: (across all 6 PRs)

With these changes, additional entities are created to expose enum, boolean, string, and integer settings based on whatever the Songpal device supports.

My motivation for making this was because I wanted to be able to control night mode, voice enhancement, and subwoofer level from Home Assistant.

Before:

After:

The additional entities may differ from device to device, so are generated dynamically based on what python-songpal reports as available.

(I don't expose playback_settings because these settings are duplicated for each input source, which seemed a bit messy. I also don't expose speaker_settings because it was giving me an Invalid Argument error and so was impossible for me to test with my device.)

I believe this change maintains backwards compatibility (existing entity unique IDs should not change, existing services are conserved).
