Refactor sdkv2 detailed diff tests

[VenelinMartinov]

This PR refactors the SDKv2 detailed diff tests to make test sharding easier. The main problem was that TestDetailedDiffSet was too large. Very similar to what #2814 does for PF.

This PR:

• Moves the SDKv2 detailed diff tests to their own folder. This should make sharing code between them easier without exposing it to the other tests.
• Splits up TestDetailedDiffSet into a few separate tests. This will allow the tests to be run on different shards.
• Moves around some of the shared code into the value_makers.go file, instead of duplicating in each test.
• Renames the tests to specify that they are for SDKv2 and renamed some of the utility functions to clarify what they do.

2c18440 has test recordings, the rest are the changes. The test recording changes are all no-ops related to the change in the struct being recorded.
