* phi2 multipack * update validation and examples for phi * more updates to phi examples * make sure to use the correct collator for phi multipack * phi needs attention mask now for multipack * if the special token already exists in the tokenizer, don't require in lora modules to save * fix qlora yml for phi, fix phi test validation * test qlora too * make sure flash attention is enabled for the test * don't use remote code for phi anymore * reduce sequence len for sample packing phi
