Replace old _shard_num implementation with shardNum() function
...
_shard_num via constant identifier (from #7624 ) has too much issues,
take a look at #16947 for example.
shardNum() function (from #27020 ) should works better.
This changes the behaviour of _shard_num slightly, now it returns nested
shard number in case of nested distributed tables (Distributed over
Distributed), but this should be minor.
v2: Rewrite _shard_num to shardNum() in TreeRewriter

Projections
...
TODO (suggested by Nikolai)
1. Build query plan fro current query (inside storage::read) up to WithMergableState
2. Check, that plan is simple enough: Aggregating - Expression - Filter - ReadFromStorage (or simplier)
3. Check, that filter is the same as filter in projection, and also expression calculates the same aggregation keys as in projection
4. Return WithMergableState if projection applies
3 will be easier to do with ActionsDAG, cause it sees all functions, and dependencies are direct (but it is possible with ExpressionActions also)
Also need to figure out how prewhere works for projections, and
row_filter_policies.
