Codec2: Detect and release component if the client process terminates

Attach death-notifier to listen to the client process termination
from the HAL process (specifically, register death-recipient with
the remote ComponentListener object).
Invoke release() on component to clean-up the resources gracefully
on client's death.
This avoids race conditions that may result from the listener's
context holding the last-strong-reference and trying to destruct
the component from within one of it's own calling contexts.
( Eg: Component destructor invoked from onWorkDone(..) )
