Refactor Set and List Diff tests to use generic utilities

[VenelinMartinov]

This PR refactors the Set and List Diff tests to use the generic diff utility functions and types introduced in #2829. This should make the tests more maintainable and more in-line with what other tests do.

861ec1f contains the changes:

• Refactors the tests to use the generic diffSchemaValueMakerPair and diffScenario types for their tests.
• Refactors the tests to use prop for top-level properties and nested_prop for nested ones, like the rest of the tests.
• Refactors the tests to use the generic runSDKv2TestMatrix test function.
• Refactors the valueMaker functions from value_makers.go to return a map[string]cty.Value instead of a cty.Value which needs to be transformed further after.
• Corrects three tests in list element removed, where the order of the elements was wrong in the changed values.

f800d2d contains the test recordings.
