Pull Request Overview
This PR adds a new Bluetooth CAP (Common Audio Profile) handover sample that demonstrates switching between unicast and broadcast audio streaming. The sample acts as a CAP Initiator and CAP Commander, showcasing the handover functionality between different audio delivery modes.
Key Changes
- Adds complete CAP handover sample application with main functionality and TX stream handling
- Creates test infrastructure for the new sample with BSim test scripts and configuration
- Updates existing CAP samples to support multiple sink streams and improve test reliability

Add CAP handover central sample that exercises the CAP handover API. It is compatible with the CAP acceptor sample assuming that the CAP acceptor sample is built with both unicast and broadcast support. It will continously switch between unicast and broadcast.
