ipa: Allow short-circuiting the ipa_context_ops

Browse source 
When an IPA module is loaded without isolation and implements the
IPAInterface internally, going through ipa_context_ops is a waste of
time. Add an operation to retrieve the IPAInterface, and use it directly
in the IPAContextWrapper.

For debugging purpose, make it possible to forcing usage of the C API by
defining the LIBCAMERA_IPA_FORCE_C_API environment variable.
