[Feature request] Bluetooth profile selector

[na4zagin3]

Expected Behavior

When I connect a Bluetooth device, I expect a Codec selector shown next to the Profile selector that can select Bluetooth codecs (e.g., "LDAC (Mobile Quality)").

Current Behavior

The "Codec" selector is missing for Bluetooth devices.

(Left: pavucontrol-qt; Right: pavucontrol)

Possible Solution

I'm not familiar with how these projects are developed but porting the functionality implemented with https://gitlab.freedesktop.org/pulseaudio/pavucontrol/-/merge_requests/54 could be an option, I think.

Steps to Reproduce (for bugs)

1. Load module module-bluetooth-discover
2. Pair a Bluetooth headphone
3. Run pavucontrol-qt
4. Open the Configuration tab

Context

Selecting Codec with pavucontrol-qt will make people switch codecs easier.
My headphone (Sony WH-1000XM2) apparently does not work well with some codecs (e.g., "LDAC (High Quality)" which was the default codec chosen for the device). It took some time for me to troubleshoot the issue. It would be great if pavucontrol-qt had the Codec selector, which would help people to find the workaround easier.
