utils: libtuning: modules: Add skeletal AGC module
Add a skeletal AGC module just so that we can have some AGC tuning values that we can use to test during development of AGC in the IPAs. As rkisp1 is the main target, we only add support for rkisp1 for now. The parameters are mostly copied from the hardcoded values in ctt, except for the metering modes.
