The init_py_*() functions are called by the top-level entry point of the
libcamera Python module to initialize different parts of the bindings.
They are declared in py_main.cpp where they are called, and defined in
separate compilation units. This results in functions being defined
without a corresponding declaration, and will generate warnings when we
enable -Wmissing-declarations.
Fix this by moving the function declarations from py_main.c to
py_main.h, and including py_main.h in the various compilation units that
need it.

We are using pybind11 'smart_holder' branch to solve the Camera
destructor issue (see the comment in this patch, or the commit
that originally added Python bindings support).
As it would be very nice to use the mainline pybind11 (which is packaged
in distributions), this patch adds a workaround allowing us to move to
the mainline pybind11 version.
The workaround is simply creating a custom holder class
(PyCameraSmartPtr), used only for the Camera, which wraps around the
shared_ptr. This makes the compiler happy.
Moving to mainline pybind11 is achieved with:
- Change the pybind11 wrap to point to the mainline pybdind11 version
- Tell pybind11 to always use shared_ptr<> as the holder for
PyCameraManager, as we use the singleton pattern for the
PyCameraManager, and using shared_ptr<> to manage it is a requirement
- Tell pybind11 to always use PyCameraSmartPtr<> as the holder for Camera
- Change the meson.build file to use a system-installed pybind11

Generate a list of pixel formats under 'libcamera.formats'.
The 'formats' is a "dummy" container class, the only purpose of which is
to contain the read-only pixel format properties.
