media: Use TRACE_ID_WITH_SCOPE in CdmPromiseAdapter

Promise IDs are just integers and cannot be unique in the process. Use
TRACE_ID_WITH_SCOPE to provide a scope to solve this.

Manually tested by grabbing a trace and inspected the trace file to
make sure the trace ID is not a 32bit integer anymore:
```
{"args":{"operation":"CreateSessionAndGenerateRequest","status":"resolved"},"cat":"media","id":"0x4722001625b09968","name":"CdmPromise","ph":"b","pid":19808,"scope":"media","tid":9112,"ts":1452599914567},
{"args":{},"cat":"media","id":"0x4722001625b09968","name":"CdmPromise","ph":"e","pid":19808,"scope":"media","tid":9112,"ts":1452600161262},
```
