This commit:
* extends existing factory interfaces to enable Mistral3 in AutoDeploy.
* adds a Mistral3 VLM factory.
* adds various model patches for pixtral (the vision model) and mistral3
to make the VLM export compliant.
* adjusts checkpoint loading code to take possible parameter name
conversions into account.
* fixes a sampling bug (the `end_id` needs to be take into account when
sampling, but it is not included in the stop words' token IDs).
