Fixes #10410. When writing partitioned tables there's no guarantee on task partitioning due to the random sampling of input data. This causes Delta log metadata checking to fail because not all of the same records are sent to the same tasks and thus not all the same records end up in a corresponding file between runs. Therefore we can't check record counts, null counts, statistics, etc. and thus we just skip metadata checking when writing to a partitioned table.
