Modification for Model Generation in quantized_cache.py

[Mefisto04]

To enhance the functionality and usability of the model generation code located in performance_optimization/quantized_cache.py, the following optimizations are proposed:

1. Handle Multiple Prompts: Implement a function to process multiple prompts in a single execution, allowing batch processing and improving efficiency.

2. Control Over Output Length and Sampling: Add parameters to allow users to specify the maximum output length and whether to use sampling or greedy decoding for text generation.

3. Batch Processing: Optimize the code to process inputs in batches, reducing the overhead of multiple calls to the model and improving performance.
