util: reimplement row level checksum utilities

[zyguan]

What problem does this PR solve?

Issue Number: ref #42747

Problem Summary:

We have implemented row level checksum utilities in #42859. However, it doesn't match the requirements for e2e checksum verification, because downstream consumers cannot calculate the checksum as tidb does. So, we reimplement checksum algorithm in this PR.

What is changed and how it works?

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)
• No code

Side effects

• Performance regression: Consumes more CPU
• Performance regression: Consumes more Memory
• Breaking backward compatibility

The overhead of checksum calculation shall be fine.
