stream-interaction: Support for triggering ducking/cork by source-output

stream-interaction: Support for triggering ducking/cork by source-output

Previously, media.role property of only sink-input is used to
determine to trigger and apply ducking or cork to sink-inputs.

On the other hand, some use cases require that source-output
also need to trigger the effect to sink-inputs. Therefore this
patch adds logic to retrieve source-ouputs to find trigger role
by checking media.role property and apply ducking/cork to sink-
inputs that meet conditions.

TIZEN_VOLUME_RAMP is replaced by __TIZEN__ in this file because
it is hard to consider to branch all #define directives.
