WangJinchao bfcec4c65b 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(%)
160     | 16          | 66439       | 63063       | -5.08
160     | 64          | 62220       | 57439       | -7.68
...
288     | 4096        | 15059       | 16278       | 8.09
288     | 8192        | 9043        | 9526        | 5.34
--------------------------------------------------------------------------------
average differ(%s)    | total_differ(%)
--------------------------------------------------------------------------------
5.70                  | -4.49
================================================================================

2. For avg cycles of operation
================================================================================
rfc4106(gcm(aes)) (pcrypt(rfc4106(gcm_base(ctr(aes-generic),ghash-generic))))
                         encryption
--------------------------------------------------------------------------------
bit key | byte blocks | base cycles | new cycles  | differ(%)
160     | 16          | 32500       | 35847       | 10.3
160     | 64          | 33175       | 45808       | 38.08
...
288     | 4096        | 131369      | 132132      | 0.58
288     | 8192        | 229503      | 234581      | 2.21
--------------------------------------------------------------------------------
average differ(%s)    | total_differ(%)
--------------------------------------------------------------------------------
