Upgrade debug mode: Add detection for default checksum algorithm breaking change

[aemous]

Description of changes:

• Added support to upgrade debug mode for detecting CRC32-by-default-in-v1 vs. CRC64NVME-by-default-in-v2.

Description of tests:

• Passed all CI (including 4 new functional tests added to verify expected behavior of the new functionality).
• Succeeded manual testing described below

Manual testing

To test the code changes, I ran the following commands:

aws s3 cp ./file.txt s3://bucket --v2-debug

I verified that the new warning is printed to STDERR.

Then, I also ran

aws s3 cp ./file.txt s3://bucket --checksum-algorithm CRC32 --v2-debug

And i verified that the new warning is not printed to STDERR.
