android: camera_device: Copy camera3 buffers in descriptor
The camera3_stream_buffer_t instances part of a capture request contain
information on the stream for which capture has been requested (size,
format and fences) and a handle to the stream's memory buffers.
This information is copied in the descriptor one piece at the time while
processing the camera3 streams to be re-used at request completion time.
Simplify the code by copying the stream information in the descriptor
at construction time.
