The type of the destination buffer in PostProcessor::process() is
libcamera::Span. libcamera::Span is used for one dimension buffer
(e.g. blob buffer). The destination can be multiple dimensions
buffer (e.g. yuv frame). Therefore, this changes the type of the
destination buffer to MappedFrameBuffer.

Configure the thumbnailer based on the thumbnail parameters given by the
android request metadata. Only the thumbnail encoder needs to be
configured, and since it is only used at post-processing time, move the
configuration out of the post-processor constructor and into the
processing step.
Also set the following android result metadata tags:
- ANDROID_JPEG_THUMBNAIL_SIZE
- ANDROID_JPEG_THUMBNAIL_QUALITY

Set the following android result metadata:
- ANDROID_LENS_FOCAL_LENGTH
- ANDROID_LENS_APERTURE
- ANDROID_JPEG_GPS_TIMESTAMP
- ANDROID_JPEG_GPS_COORDINATES
- ANDROID_JPEG_GPS_PROCESSING_METHOD
And the following EXIF fields:
- GPSDatestamp
- GPSTimestamp
- GPSLocation
- GPSLatitudeRef
- GPSLatitude
- GPSLongitudeRef
- GPSLongitude
- GPSAltitudeRef
- GPSAltitude
- GPSProcessingMethod
- FocalLength
- ExposureTime
- FNumber
- ISO
- Flash
- WhiteBalance
- SubsecTime
- SubsecTimeOriginal
- SubsecTimeDigitized
Based on android request metadata.
This allows the following CTS tests to pass:
- android.hardware.camera2.cts.StillCaptureTest#testFocalLengths
- android.hardware.camera2.cts.StillCaptureTest#testJpegExif

Embed a Jpeg-encoded thumbnail into Exif metadata using the Thumbnailer
class that got introduced.
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.
