SDV 2.0: Update metadata auto-detection to the new V2 format

[R-Palazzo]

Resolve #2957
86bbgka4c

Here are a few points I wanted to check:

1. My assumption was that we should not detect ranges for columns with the unknown sdtype. Does that make sense?

2. I created two test utility methods to make the metadata assertions easier to maintain, since the new range keys make the expected metadata much larger (range_values especially) and hardcoding all the values did not seem ideal:

   • compare_metadata(metadata, expected_metadata) checks that the existing metadata detection behavior is preserved and validates the expected metadata keys.
   • compare_ranges(metadata, data) validates the detected range values against the original data.
