[FEA] [Delta Lake] Add support for new metrics in MERGE

[andygrove]

Is your feature request related to a problem? Please describe.

Delta Lake 2.4 adds some new metrics for MERGE operations:

'numTargetRowsMatchedUpdated': '0', 
'numTargetRowsMatchedDeleted': '0',
'numTargetRowsNotMatchedBySourceUpdated': '0',
'numTargetRowsNotMatchedBySourceDeleted': '0'

Describe the solution you'd like
We should ensure that we have tests that generate valid metrics on CPU and then determine what we need to do on GPU to match.

Describe alternatives you've considered

Additional context

[andygrove]

Note that we currently fall back to CPU for queries involving NOT MATCHED BY SOURCE. Tracking issue is #8415

[andygrove]

This is related to #8415 but I don't think it is a duplicate since we should produce zero metrics in the case where we do run a MERGE on GPU and there is no NOT MATCHED BY SOURCE clause.
