Jesse Gross c826e57475 runner.go: Better abstract vision model integration 
-Update mllama to take the cross attention state as embeddings in
a batch, more similar to how Llava handles it. This improves
integration with the input cache.
-Pass locations in a prompt for embeddings using tags similar to Llava.
-Abstract interface to vision models so the main runner accesses Clip
and Mllama similarly

Subject: [PATCH] add mllama support
mllama adds cross-attention layers to the standard llama architecture
it also requires a way to input a new tensor: cross_attention_state
once per generation
cross-attention layers don't change and so they are cached in the
kv cache once per run
remaining is to implement the cross attention mask
