Subject: android: jpeg: Support an initial set of EXIF metadata tags

Create a Exif object with various metadata tags set, just before
the encoder starts to encode the frame. The object is passed
directly as libcamera::Span<> to make sure EXIF tags can be set
in a single place i.e. in CameraDevice and the encoder only has
the job to write the data in the final output.
