ipa: Move core IPA interface documentation to a .cpp file

Moving the core.mojom documentation to its corresponding .cpp file
(core_ipa_interface.cpp). This will allow Doxygen to generate the
documentation for IPABuffer, IPASettings and IPAStream structures.
Since the .mojom files are placed in include/ directory, the .cpp file
will live in $sourcedir/src/libcamera/ipa/ - which can also contain
documentation for other mojom generated IPA interfaces in subsequent
commit.

Also hide the constructors in generated IPA interface from doxygen,
via  #ifndef __DOXYGEN__. These constructors provide no major value in
documenting them, instead will spew out doxygen warnings during the
build.
