This change updates the parser grammar and the TableChange API to allow representing tables that have CLUSTER BY clauses on expressions (eg. `CLUSTER BY (variant_get(col, ...))` instead of just CLUSTER BY `(col)`. The goal is to make this TableChange backward-compatible with connectors that only support clustering by raw columns, while allowing connectors to opt-into supporting some transforms if they are present.
