Construct a FrameBuffer for every buffer given in the camera3Request
and add it to the libcamera Request on the appropriate stream.
The correct stream is obtained from the private data of the camera3_stream
associated with the camera3_buffer.
Comments regarding supporting only one buffer are now removed, and
FrameBuffers have their lifetime tracked in the Camera3RequestDescriptor
to ensure they are released when the Request is completed.

Introduce a vector storing a CameraStream to track and maintain
state between an Android stream (camera3_stream_t) and a libcamera
Stream.
Only the index of the libcamera stream is stored, to facilitate identifying
the correct index for both the StreamConfiguration and Stream vectors.

When the IPU3 pipeline only provided streams to applications that came
from the ImgU it made sense to have a generic function to configure all
the different outputs. With the addition of the RAW stream this begins
to be cumbersome to read and make sense of in the PipelineHandlerIPU3
code. Replace the generic function that takes a specific argument for
which sink to configure with a specific function for each sink.
This makes the code easier to follow as it's always clear which of the
ImgU sinks are being configured without knowing the content of a
generically named variable. It also paves the way for future
improvements.

When the IPU3 pipeline was first developed sinks of the ImgU that where
not active still needed to have buffers allocated to allow streaming to
start. This is no longer true, it's enough that the sinks have imported
buffers to allow streaming to start. As we already need to import
buffers for stream that are active we can align the two cases and always
import buffers.
With this there is no longer a reason to store the allocated
FrameBuffers to keep them alive and the vector tracking them can be
