android: jpeg: encoder_libjpeg: Allow encoding raw frame bytes
Allow encoding frames which are directly handed over to the encoder
via a span or vector i.e. a raw frame bytes. Introduce an overloaded
EncoderLibJpeg::encode() with libcamera::Span source parameter to
achieve this functionality. This makes the libjpeg-encoder a bit
flexible for use case such as compressing a thumbnail generated for
Exif.
