libcamera: stream: Shorten access to the bufferPool

Browse source 
All interactions with the Stream's buffers currently go through the
BufferPool. In order to shorten accessing the buffers array, and eventually
restrict access to the Stream's internal buffer pool, provide operations to
access, create and destroy buffers.

It is still possible to access the pool for pipeline handlers to
populate it by exporting buffers from a video device to Stream's pool.
