[nrf fromtree] tests: bluetooth: tester: Add ASE ID when configuring codec

- We want to add the ASE ID to a stream as early as possible
  to make sure the events coming from BTTester to Auto-PTS
  contains the correct information.
- Previously the events that came before stream_configured
  would contain ASE ID 0, regardless of actual value.
