…on (#1900) This PR adds support for model caching, to improve 2nd+ load time. It allows the `genai_config.json` to specify a 'cache_dir' provider option (e.g. 'openvino_cache'). When set, it will instruct the OpenVINO EP to create a cache directory within the model folder (by default, unless an absolute path is specified). OpenVINO will save compiled blobs to this directory, and then read on successive runs. This drastically reduces model load time for the 2nd+ runs. This PR moves all OpenVINO-specific provider option handling into a `OpenVINO_AppendProviderOptions` API, provided by `openvino/interface`. The changes in `model.cpp` are mainly to remove all OpenVINO-specific handling that was grouped with the rest of the other EP's, as that's now handled within `OpenVINO_AppendProviderOptions`.
