bluez5: feature request: AAC decoding

If you are filing this issue with a regular release please try master as it might already be fixed. Also test with PulseAudio because if it doesn't work there it's not going to here either.

Bluetooth Radio, Bluetooth Headset, Desktop Environment, Distribution, Version (Bluez, Kernel, and PipeWire): any

Description of Problem: Only SBC and aptX support decoding

How Reproducible: Connect a phone as source and see that it uses SBC while AAC is installed.

Actual Results: SBC is used (I didn't build aptX, only SBC and AAC)

Expected Results: AAC is used, FDK-AAC has decoder functions

Additional Info Eg. Additional Kernel Patches, pw-dump > file (As Attachment Please): Edit: I guess LDAC cannot be decoded because sinks with LDAC support bust be licensed by Sony, only LDAC encoder is free.
