Introduce a helper function in Exif class for setting the thumbnail
data.

PostProcessorJpeg doesn't have the ownership of CameraDevice given
in the constructor. To clarify it, this makes the member variable
constant.

In PostProcessor::process(), the |source| argument doesn't have
to be a pointer. This replaces its type, const pointer, with
const reference as the latter is preferred to the former.
libcamera::Span is cheap to construct/copy/move. We should deal
with the type as pass-by-value parameter. Therefore this also
drops the const reference in the |destination| argument.

Port the CameraStream's JPEG-encoding bits to PostProcessorJpeg.
This encapsulates the encoder and EXIF generation code into the
PostProcessorJpeg layer and removes these specifics related to JPEG,
from the CameraStream itself.
