Support Partition stats, column stats, bloom filters creation using SQL

Users cannot create partition_stats, column_statas and bloom_filters indexes through SQL. They can only be created through datasource. There are workarounds e.g. one can create expression index using column_stats with identity function of a column. But, we should provide more standard sql for building these indexes.

## Comments

13/Mar/25 14:12;codope;Currently, columns being indexed in colstats (and by extension partition_stats too) are being tracked in index definition. So, when user adds a column stats are being colelcted automatically, so adding sql functionality is not a blocker. Downgrading from Blocker to Major. Still, would be nice-to-have a sql command to generate stats.;;;
