When file output is requested from cam app, it simply dumps the
processed data and it must be converted to a readable image format
manually. Let's add support for PPM output file format to make files
produced by cam directly readable by image display and processing
software.
For now, only BGR888 output format, which is the simplest one to use, is
supported but nothing prevents adding support for other output formats
if needed. Nevertheless, they would typically need byte reordering or
other conversions for PPM file format. It may be better to find a way to
dump the image data in other output formats directly using some of the
already existing file formats or raw file format converters.

A new warning has been introduced to gcc-13 that produces a false
positive on the cam file sink object:
src/cam/file_sink.cpp:92:45: error: possibly dangling reference to a temporary [-Werror=dangling-reference]
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];
| ^~~~
src/cam/file_sink.cpp:92:81: note: the temporary was destroyed at the end of the full expression '(& buffer->libcamera::FrameBuffer::metadata())->libcamera::FrameMetadata::planes().libcamera::Span<const libcamera::FrameMetadata::Plane>::operator[](i)'
92 | const FrameMetadata::Plane &meta = buffer->metadata().planes()[i];
| ^
cc1plus: all warnings being treated as errors
Workaround this issue by refactoring the code to take a local const
copy of the bytesused value, rather than a local const reference to the
plane.

Multiple source files in the src/apps/cam/ directory are used by cam,
qcam and lc-compliance. They are compiled separately for each
application. Move them to a new src/apps/common/ directory and compile
them in a static library to decrease the number of compilation
operations.

When libtiff-4 is not found, the private camera_ member of the FileSink
class is set but never used. This causes a compilation error with clang:
In file included from ../../src/apps/cam/file_sink.cpp:19:
../../src/apps/cam/file_sink.h:39:27: error: private field 'camera_' is not used [-Werror,-Wunused-private-field]
const libcamera::Camera *camera_;
Fix by making the camera_ member field conditional on HAVE_TIFF.

The cam and qcam test application share code, currently through a crude
hack that references the cam source files directly from the qcam
meson.build file. To prepare for the introduction of hosting that code
in a static library, move all applications to src/apps/.
