Add a basic image Thumbnailer class for the frames being captured.
Currently, the thumbnailer can scale NV12 frames. It shall be used
to generate a thumbnail image for EXIF metadata, in the subsequent
commit.

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().

The C++20 std::span class, after which Span is modelled, specifies four
constructors as explicit when extent is not dynamic_extent. Align our
implementation with those requirements.
A careful reviewer may notice that this change addresses five
constructors, not four. The reason is that the two constructors taking
Container and const Container parameters are not specified in C++20,
which uses a single constructor taking a range parameter instead. As
ranges are not available in C++17, the Container constructors are our
best effort at providing a similar feature.

The ControlValue<T> constructor for non-array values is a template
function that participates in overload resolution for all T types that
are not Span or std::string. Other T types that are not supported then
result in a compilation error.
This causes issues when calling an overloaded function that can accept
both a ControlValue and a Span with an std::array<U> parameter. The
first overload will be resolved using implicit construction of a
ControlValue from the std::array<U>, while the second overload will be
resolved using implicit construction of a Span<U> from the
std::array<U>. This results in a compilation error due to an ambiguous
function call.
The first overload is invalid, selecting it would result in a
compilation error in the ControlValue constructor, as the
ControlValue<T> constructor doesn't support std::array<U> for type T.
The compiler can't know about that, as overload resolution happens
earlier.
To fix it, we can disable the ControlValue<T> constructor for
unsupported types T, moving the type check from compilation of the
function to overload resolution. The constructor will not participate in
overload resolution, and the call won't be ambiguous. The end result is
the same for unsupported types, compilation will fail.

The rkisp1 and simple pipeline handlers can fail to register any camera,
if initialization of all the detected cameras fail. In that case, they
still return success from their match function. As no camera gets
registered, the pipeline handler is immediately destroyed, releasing the
acquired media devices, and the camera manager immediately tries to
match the same pipeline handler with the same media device, causing an
endless loop.
Fix it by returning false from the match function if no camera gets
registered.

Enable warnings for shadowed variables as defined at:
