audio: dai-zephyr: Add state change on DAI trigger

Currently, the DAI component's state is not updated on
dai_trigger() operation, which leads to pipeline_comp_copy()
skipping the dai_copy() operation (since the DAI component
never transitions to the ACTIVE state). To fix this, add
a state transition in dai_comp_trigger_internal(). Also,
make sure not to trigger the DAI component if already in
the requested state.
