Do not acquire lock for total_bytes/total_rows for Buffer engine
...
When Buffer() is under preassure, acquiring per-layer lock may take
significant time. And so the following query may take significant amount of time:
SELECT total_bytes, total_rows FROM system.tables WHERE engine='Buffer'

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.
