1369c0b7c3 utils: checkstyle: Add support for clang-format
clang-format produces better results than astyle as it can better match
the libcamera coding style. Default to clang-format over astyle, fall
back to astyle if clang-format isn't found, and add a --formatter
command line option to select a formatter manually.

0908669834 Documentation: coding_style: Add object ownership rules
Object ownership is a complex topic that can lead to many issues, from
memory leak to crashes. Document the rules that libcamera enforces to
make object ownership tracking explicit.

This is a first version of the rules and is expected to be expanded as
the library is developed.

e42683b40d Documentation: Add placeholder for Doxygen-generated API documentation
Until we have better Sphinx + Doxygen integration, replace the relative
external link to the API documentation with a placeholder directory,
which will be populated with the Doxygen-generated doc when exporting
documentation to the website. This is needed as the Sphinx documentation
is exported to the root of the website, linking to ../api-html is thus
not possible.

53c4d4c34f Documentation: Generate source code documentation using Doxygen
Extend the documentation build system to automatically generate
documentation from source code using Doxygen. This is currently separate
from the sphinx documentation, and should be integrated using the
breathe (and possibly exhale) extensions.

As the Documentation/meson.build file needs to reference the variables
holding the source files, move the Documentation directory to the end of
the subdirs() in the top-level meson.build.
