Add asInputSink() to IComponent

By making IComponent present itself as an IInputSink, the wrapper code
can be made to execute in the same process as the IComponent instance,
hence reducing an IPC hop in the case where an InputSurface comes from a
different process.

Test: make cts -j123 && cts-tradefed run cts-dev -m \
CtsMediaTestCases --compatibility:module-arg \
CtsMediaTestCases:include-annotation:\
android.platform.test.annotations.RequiresDevice
