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.

std::map::at() searches std::map by the given key. The commit
e1f9fdb8a5bd ("android: camera_device: Remove shadowing FrameBuffer
usage") uses it with 0 to intend to accessing the first element of the
map, but actually access the element whose key is nullptr. This causes
the crash because the map doesn't have the element with nullptr. This
fixes the issue by replacing the std::map::at() operation by
std::map::begin().

reference as the latter is preferred to the former.
libcamera::Span is cheap to construct/copy/move. We should deal

Introduce a PostProcessor interface for the streams that require any
kind of processing (refer to CameraStream::Type) for their consumption
by the HAL layer. The PostProcessor interface can be configured via
configure() and the actual processing can be initiated using process().
The post-processing layer can be extended to have multiple post
processors for various stream configurations. As of now, we only have
one post processor (JPEG), hence the subsequent commit will port its
function to this interface.

The Android camera framework provides for each buffer part of a capture
request an acquisition fence the camera HAL is supposed to wait on
before using the buffer. As the libcamera HAL runs in the camera service
thread, it is not possible to perform a synchronous wait there.
Introduce a CameraWorker class that runs an internal thread to wait
on a set of fences before queueing a capture request to the
libcamera::Camera.
Fences completion is handled through a simple poll, similar in
implementation to the sync_wait() function provided by libdrm.
