### This PR needs to wait `gguf` package version update and still work in progress.
- This PR aims to add dequantization support for the remaining `ggml_types`. And clean up the current ggml dequantization implementation.
- Since `llama.cpp` has added numpy dequantization implementation on `gguf-py` in https://github.com/ggerganov/llama.cpp/pull/8939, we can dequantize most of ggml tensor easily in one line.
