libcamera: FrameBuffer: Add a method to copy buffer content
This method may be used to memory copy a whole FrameBuffer content
from another buffer. The operation is not fast and should not be used
without great care by pipelines.
The intended use-case is to have an option to copy out RAW buffers from
the middle of a pipeline.
