Enable Llama 3.2 11B Vision Instruct in OpenVINO

I request to add support for the "Llama 3.2 11B Vision Instruct" model so that we can quantize the model using optimum-cli. Currently, I get an error while trying to quantize and download the Llama 3.2 11B Vision Instruct model.

_"ValueError: Trying to export a mllama model, that is a custom or unsupported architecture, but no custom export configuration was passed as `custom_export_configs`"_

Start by reproducing the Llama 3.2 11B Vision Instruct quantization failure with optimum-cli and trace the mllama export error. The work is done when the model can be downloaded and quantized without requiring an unsupported-architecture error.

Written by the indexing model from the issue text.
