The pre-trained MPT models do not include 'bias' parameters. This PR is intended to make llama.cpp compatible with PhoGPT and SEA-LION models for Southeast Asia languages, that were pre-trained using the MPT architecture but with the addition of 'bias'.
This PR is based on @nviet 's commit with modifications to make 'bias' parameters optional.
