Add a metric changefeed_tables_watched, that takes the number of tables watched across all changefeeds and aggregates them together. We would expect this number to always be larges than num_changefeeds, since each changefeed watches at least one table.
We may want to change the name if split column tables are counted as multiple "watched tables" even though they are logically one table.
This is important for the cloud 2.0 work and should be backported.
