media: iris: Add support for buffer management ioctls for encoder device

Implement support for queuing and dequeuing input and output buffers
for the encoder video device using the appropriate V4L2 buffer
management ioctls.

This enables userspace applications to manage streaming buffers
required for encoding operations.
