Add Script to Calculate Summary Information for Benchmark Results

[kiddyjinjin]

Purpose

This PR introduces a new script to calculate summary information for benchmark results, aimed at providing insights into the average speedup for each operation categorized by data type.

Changes Made

• Added a new script summary_for_plot.py that processes benchmark log files.
• Implemented functionality to calculate and display average speedups for different data types.
• Included conditional logic to handle query mode and provide backward compatibility notices.

Usage

To generate summary information from benchmark logs, run the following command:

python summary_for_plot.py path_to_your_log_file.log

I suggest adding a shell script to ensure the order of operator benchmarks.

Since the command for generating benchmarks is quite flexible (it might specify op_name, a specific file, or simply run all operations without any specification), it would be challenging to pre-sort the operations to be benchmarked. However, sorting the operations in the benchmark results after the run is a great suggestion.
