crypto: tcrypt - add script tcrypt_speed_compare.py
Create a script for comparing tcrypt speed test logs.
The script will systematically analyze differences item
by item and provide a summary (average).
This tool is useful for evaluating the stability of
cryptographic module algorithms and assisting with
performance optimization.
Please note that for such a comparison, stability depends
on whether we allow frequency to float or pin the frequency.
The script produces comparisons in two scenes:
1. For operations in seconds
================================================================================
rfc4106(gcm(aes)) (pcrypt(rfc4106(gcm_base(ctr(aes-generic),ghash-generic))))
encryption
--------------------------------------------------------------------------------
bit key | byte blocks | base ops | new ops | differ(%)

--------------------------------------------------------------------------------
average differ(%s) | total_differ(%)

2. For avg cycles of operation
================================================================================
