Support a generic Comfy format for text encoder loras.

This is a format with keys like:
text_encoders.clip_l.transformer.text_model.encoder.layers.9.self_attn.v_proj.lora_up.weight

Instead of waiting for me to add support for specific lora formats you can
convert your text encoder loras to this format instead.

If you want to see an example save a text encoder lora with the SaveLora
node with the commit right after this one.
