feat(FIR-10764): Snapshot support

[ptiurin]

Description

This change allows us to use DBT's Snapshot feature. We've been previously blocked by two things: MERGE query and CREATE OR REPLACE TABLE. Former was rewritten for the snapshotting purpose with INSERT and UPDATE queries. The latter was achieved the same way as in table materialisation (which snapshot does not go through).
