libcamera: ipa_module_info: update struct to allow IPA matching

Browse source 
We need a way to match pipelines with IPA modules, so add fields in
IPAModuleInfo to hold the IPA module API version number, the pipeline
name, and the pipeline version.

The module API version is used to determine the layout of struct
IPAModuleInfo.

Also update IPA module tests and Doxygen accordingly. Doxygen needs to
be updated to accomodate __attribute__((packed)).
