libcamera: ipa_module: verify IPA module API version upon loading
The IPA module API version determines the layout of struct
IPAModuleInfo. If this version number does not match, then it means that
the IPA module information structure can't be interpreted, and the
module can't be used. Validate this version number upon loading the
IPA module info from the IPA shared object.
