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
